BugID: 1741544	Desktop blacks out after HW accelerator is disabled with MS property.	GDI	Windows* XP	Intel(R) 945GM Express Chipset
Resolution Description: Root Cause When we reduce Hardware Acceleration to none, we get DrvCopyBits call with source PDEV not activated. The issue happens because DrvCopyBits returns TRUE without actually doing anything since source Pdev is not activated. We can punt the call to GDI if we could not handle. Issue does not happen when we punt the call instead of returning TRUE. Fix Given:

BugID: 1612651

Japanese IME tool bar is flashing during DirectDraw test of dxdiag.exe.

 GDI

 Windows* XP

Intel(R) 855GM Chipset
Intel(R) 865G Chipset
Intel(R) 915G Express Chipset

Intel(R) 915GM Express Chipset

Intel(R) 945G Express Chipset
Intel(R) 945GM Express Chipset

Resolution Description:

Root Cause: GDI and DDraw do not communicate properly. While DDraw is in exclusive mode, GDI should not draw in that mode. DrvCopyBits() is called to clear and draw the toolbar. The flip is pending and DrvCopyBits() does not wait because it is not a DDraw function.
Root Cause: GdiWaitFlipPending() is called in the DrvCopyBits() to wait for the pending flip to be executed in exclusive mode before the IME tool bar is drawn.

BugID: 1629041

 Colors become unusual when making the window smaller in playing WMV_HD file.

 DD

 Windows* XP

 Intel(R) 915GM Express Chipset

Intel(R) 945G Express Chipset

Resolution Description:

Root Cause: This bug occured after Gmm optimized YUV IMC_2_4 surfaces to only map in the planar pages that are used based on the width during surface creation. DDraw assumed that the entire surface up to the pitch was usable (mapped in). The bug appeared when using these surfaces for downscaling the overlay.

Root Cause: this bug can be fixed by using the mapped page in YUV pages for the temporary YUV surfaces when downscaling.

BugID: 1633587

 Some residual screen on desktop when running 3DLabs in the pivot mode.

 OGL

 Windows* XP

 Intel(R) 945G Express Chipset

Resolution Description:

Root Cause: The corruption occurred because the app window was not clipped by the screen. The fix clips the windowRect by the resolution of the screen.

Intel(R) 915GM Express Chipset

Intel(R) 945G Express Chipset
Intel(R) 945GM Express Chipset

Resolution Description:

Root Cause: The COPP session data was originally being allocated as pageable, which may have been causing sporadic BSOD when the session data was hit while paged out. Redo the allocation to be unpageable.

BugID: 1668519

 Network communication initiated to Domain Controller on every right click or CP access. (GER)

 CUI2

 Windows* XP

 Intel(R) 915GM Express Chipset

Intel(R) 945G Express Chipset

Resolution Description:

Root Cause: The string "EVERYONE" has a different meaning for German OS. In German OS, it should be "Jeder". By having "EVERYONE" in the CUI code, it causes the German OS to do a domain lookup for "EVERYONE" and network communication.

BugID: 1625487

 There is no data in color quality and screen resolution items, and the display mode cannot be switched to HDTV with modified BIOS.[REG]

 AIM

Windows* XP

 Intel(R) 855GM Chipset

Resolution Description:

Root Cause: When queried for HDTV modes, AIM component used to get the HDTV mode list and the function assign supported and preferred standards to that mode list. But in the latest versions of gfx driver, AIM does not get any mode list.
Fix Description: 1) Do not eWindows* XPect the mode list from CUI. Add the HDTV modes as well as supported and preferred standards when queried for HDTV caps. This fix is ported from UAIM code base. 2) When queried for minimum resolution, OS returns 800x600. But for HDTV, it should be 640x480. The changes are in igfxdev\DevMode.cpp.

BugID: 1658723

 When CUI2 switches to CRT+TV(DDC) w/ DTCM, TV blanks out. (Driver crash)[ICT]

 GDI

 Windows* XP

Intel(R) 915GM Express Chipset

Resolution Description:

Root Cause: GDI sending an invalid combination of display device list (such as CRT+CRT) to SoftBios is resulting mode table list shortage and eventually retuning zero.
Fix Description: GetRegistryDisplayDevices() function is revamped to appropriately handle DISPLAY_CURRENT_CONFIG, DISPLAY_1_CONFIG and DISPLAY_2_CONFIG. The code update ensures that GDI does not generate an invalid display device combination.

BugID: 1683821

BugID: 1663757

 MCCS: Values in color tab cannot be reset to default after they changed.

 CUI2

Windows* XP

 Intel(R) 915G Express Chipset

Resolution Description:

Root Cause: The MCCS controls were not initialized once the values changed, so slider dint retained its position.

Fix Description:

BugID: 1660015

 The EFP radio button still displays on IGT page after unplugging the EFP and then resuming from Hibernation state with IGT page opened.[REG]

 CUI2

 Windows* XP, Windows* 2000

 Intel(R) 915GM Express Chipset, Intel(R) 915GM Express Chipset

Resolution Description:

Root Cause: An expected behavior until CUI handles PBT_APMRESUMEAUTOMATIC. We require clear requirements on why PBT_APMRESUMEAUTOMATIC should be handled and their side effects. This may be added after a through Impact analysis. It is proved in MSDN for PBT_APMRESUMEAUTOMATIC attached.

Transient green grabage displays when Live TV, Video Playabck, and DVD is launched in Media Center.

DD, DVD

XP, MCE

Intel(R) 945GM Express Chipset, Intel(R) 945G Express Chipset

Resolution Description:

Root Cause: MCE is using the YUY2 texture surfaces without initialize them. During LiveTV, DVD, or pre-corded video playback in MCE 2005, the transient green (sometimes also pink squares) display for second when switching from window viewing to full screen. Expectation is a solid black screen.

Fix Given: We decided not to fix the bug becuase the OEM that wanted it is happy enough that the next version of MCE does not show this issue. This issue was a MS problem becuase they did not choose to initialize their memory before they displayed it to the screen.

BugID: 1640528

Transient green grabage displays when Live TV, Video Playabck, and DVD is launched in Media Center.

DD, D3D, DVD

XP, MCE

Intel(R) 945GM Express Chipset, Intel(R) 945G Express Chipset

Resolution Description:

Root Cause: MCE is using the YUY2 texture surfaces without initialize them. During LiveTV, DVD, or pre-corded video playback in MCE 2005, the transient green (sometimes also pink squares) display for second when switching from window viewing to full screen. Expectation is a solid black screen.

Fix Given: MCE is using the YUY2 texture surfaces without initialize them. We try to init the YUY2 texture surfaces as 0x8000 (black in YUV domain) by HW.

BugID: 1646770

Garbage shows on screen while testing Coredraw with Pivot mode.

ROTATION

Windows* 2000, Windows* XP

Intel(R) 945G Express Chipset

Resolution Description:

Root Cause: This is introduced due to DrvStrokePath optimization in rotation. The optimization takes each line in path object, rotate the coordinates and draws the line to the Frame buffer. While converting the float coordinates to long, there is data lost from the conversion. One pixel difference in calculation changes the slope of the line. A path drawn with non optimized and optimized path can have difference.

Fix Description: DrvStrokepath optimization in Rotation is disabled.

BugID: 1625842

The position arrows in TV/Advanced Settings are not in accordance with the orientation chosen.

CUI2

Windows* XP

Intel(r) 915GM Chipset

Resolution Description:

Root Cause: Scaling issue related to 3D settings bug.

Fix Given: The calling sequence changes for an active detect was done before getting the current configuration.

BugID: 1649176

FBC stride to use bpp that corresponds to current mode, C3SR wmark to use 32bpp always for calc

RESOURCE MANAGER

Windows* XP

Intel(r) 915GM Chipset, Intel(R) 945GM Express Chipset, Intel(r) 855GME Chipset

Resolution Description:

Root Cause: Past directions from HW to use 32bpp for FBC stride calculation for all bpp modes no longer valid. The larger than expected stride threshold for 16bpp modes caused display corruption. Using the bpp of the current mode fixes the issue. Then, for C3SR, 16bpp modes were seeing flicker on Calistoga. There is a HW arch issue for all platforms for C3SR. Using 32bpp for watermark calculations is the workaround.

Fix Given: Changed FBC stride calculation to use the actual bpp of the current mode instead of a constant 32bpp. ALso changed C3SR watermark calculations to always use 32bpp. This is a workaround for a HW issue in lower bpp modes. We will use 32bpp for all watermark calculations.

BugID: 1624597

CUI2_Some help tips can not be reached by right clicking, but can be reached by the question mark

CUI2

Windows* XP

Intel(R) 945G Express Chipset

Resolution Description:

Root Cause: Notify property is missing few controls.

Fix Given: Added Notify property into the resource file and also added controls which are not having strings IDs in commonutils.cpp.
