Description Tilman Sauerbeck 2006-06-07 05:09:27 UTC 
When I enable color tiling on my r300 (R420 JI [Radeon X800PRO]) Evas
applications that use the Evas Software X11 engine don't render properly
anymore. It works when I use Evas' XRender backend or when I switch off color
tiling.

I guess Evas isn't the only application that's affected by this, but so far I
didn't find another one. I'm sure it's not a bug in Evas either since it only
shows if color tiling is enabled.

To reproduce:
Enable color tiling on a r300 card and run evas_software_x11_test.
It should display a small window (240x320), but it's drawing noise all over the
width of the screen, but with the same height as the window should have (ie,
320). I'll attach two screenshots that show the effect.

This bug occurs with xorg-xf86-video-ati 6.6.0.

XAA or EXA?
Comment 4 Tilman Sauerbeck 2006-06-07 06:08:24 UTC 
EXA.

The problem vanishes when I enable XAA instead.
