I have this hardware plugged in: 01:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200 SE] (rev 01) (prog-if 00 [VGA controller]) Subsystem: Hightech Information System Ltd. Excalibur 9200SE VIVO 128M Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 16 Memory at c8000000 (32-bit, prefetchable) [size=128M] I/O ports at b800 [size=256] Memory at d7ef0000 (32-bit, non-prefetchable) [size=64K] Expansion ROM at d7ec0000 [disabled] [size=128K] Capabilities: [58] AGP version 2.0 Capabilities: [50] Power Management version 2 Kernel driver in use: radeon Kernel modules: radeonfb After commit c0c33dab44e6966b1702d4e8cfba3537fc6e2d5c ("Fix off by one in EXA composite limit checking") composited dual-monitor setup (2 * 1024x768, Virtual 2048*1024 in xorg.conf) is broken, windows can just disappear if i move them too close to right screen's right edge. Bug visible only while xcompmgr or E16's builtin compositing manager is active. Reverting this commit fixes corruption.
Created attachment 21457 [details] xorg.conf
Created attachment 21458 [details] X log For some reason, driver still shown 6.9.0 as module version
I'm not able to reproduce this on my rv280. Can you get a picture of the corruption? Is it just specific apps?
Created attachment 21500 [details] image corruption Sorry, this is most visible with partially-transparent windows I will try do disable DFS also , one moment ...
No difference between DFS on/off.
reverted back to 2047: e55598cc1b35d398c9eb2c3946df71456775f621 Looks like it's a render target limit, 2k textures are probably ok.
