Description Didier 2002-09-08 18:49:08 UTC
Description of Problem:

On an ATI R128/Radeon i386 platform, when running the VMware emulator
(http://www.vmware.com) in full-screen mode within a DRI-enabled XFree86
session, screen corruption occurs in the vicinity of the mouse pointer.
As this is due to a bug in the XFree86 DRI code, other applications may be
affected too.

Version-Release number of selected component (if applicable):

XFree86 4.2.x, all versions.

How Reproducible:


Steps to Reproduce:
1. Enable DRI, start Xfree86 
2. Start VMware session, run in full-screen
3. Drag Windows windows with mouse, scroll windows, etc.

Actual Results:

The screen gets cluttered.

Expected Results:

No screen corruption.

Additional Information:
As VMware is a well-known and widely used application, and the ATI chipsets are
quite commoditized, I would expect this problem to have a wide impact.

Fortunately, as of today, Mr. Michel Daenzer posted a patch which finally fixes
this problem (tested on an IBM ThinkPad A30p, ATI Radeon Mobility M6).


Patch against XFree86 4.2 attached (courtesy of Mr. Daenzer).

Comment 2 Mike A. Harris 2002-09-10 03:15:51 UTC
Thanks, I'll chat with Michel about the patch, and add it to future builds
if it is safe/sane.  That probably means yes.  ;o)

Comment 3 Mike A. Harris 2002-09-10 08:41:16 UTC
Ok, I finally caught Michel in IRC, and have applied the patch
to my latest private build.  It will appear in a future rawhide
XFree86 version at some point when I merge my private build
to rawhide.

Thanks very much for the bug report, and for attaching the patch.
