Description Chris Rankin 2008-09-17 08:59:31 UTC 
Created attachment 18958 [details]
World of Warcraft login screen, showing white line along the bottom of the screen.

After upgrading the drm/radeon kernel modules from 2.6.26.4 to those from Git, I am noticing a white line along the bottom of the WoW login screen that extends a small distance up the right-hand edge as well.

I have created a screen-capture JPEG of the problem, but the although the feature *is* visible, it is hard to spot beyond the general crapness of the picture. I don't know why screen capture is so broken with the R300 - the original screen looked fine (apart from the white line), and capture worked just fine for my R200.

Running WoW in a window (e.g. 1400x900 or 1024x768) instead of full-screen at 1680x1500 creates a flickering white(?) line along the bottom and right-hand edges of the image instead.

This is all with a Radeon 9550, dual P4 Xeon, running with a vanilla 2.6.26.4-SMP kernel and the Fedora 9 userspace environment.

This is probably due to a cliprect fix which needs the corresponding fix in Mesa 7.1.

I am using Mesa from Git, too:
OpenGL renderer string: Mesa DRI R300 20060815 AGP 8x x86/MMX/SSE2 TCL
OpenGL version string: 1.3 Mesa 7.3-devel
Comment 5 Chris Rankin 2008-10-06 10:26:44 UTC 
This is almost certainly due to Wine using the r300_dri object that comes with Fedora 9 (Mesa 7.1 rc1) rather than the correct r300_dri object from Mesa-git. This is because my installation was accidentally using AIGLX instead of direct rendering.
