Red Hat Bugzilla – Bug 73678
Screen corruption when running full-screen VMware under DRI-enabled XFree86
Last modified: 2007-04-18 12:46:28 EDT
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
Version-Release number of selected component (if applicable):
XFree86 4.2.x, all versions.
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.
The screen gets cluttered.
No screen corruption.
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).

DRI patch against ati_dga and radeon_dga
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)
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
Thanks very much for the bug report, and for attaching the patch.
