Summary: radeon-rewrite: crash in glCopyTexSubImage2D
Product: Mesa
Version: unspecified
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/r300
AssignedTo: [email protected]
ReportedBy: [email protected]
When running Team Fortress 2 in Wine with the DRI driver from the
radeon-rewrite branch(with KMS et al set up), the game crashes in
glCopyTexSubImage2D and in turn brings the X server down.
This is the backtrace I got from the crash:

<more wine code following>
The X server writes the following:
RADEON DRM CS failure - corruptions/glitches may occur -22
bufmgr: last submission : r:192 vs g:534769664 w:3356160 vs v:110455596
And then the screen seems dead. ssh still works
It may be possible that Wine calls glTexSubImage2D with a deleted texture name
or the 0 texture bound. Team Fortress 2 releases the current rendertarget, and
Wine does not handle this properly, resulting in complaints from the GL driver
with other drivers. The logs indicate that I get the same errors back from
Mesa, so this might be a red herring, and the crash occurs during a valid
operation. In any case, the X server should not crash, no matter how badly the
app behaves.
