Apologies if this isn't a radeonsi issue. Before today I've never tested weston so have no knowledge of past behavior. R9285. Issue happens with weston alone or started from within X. Weston its self renders OK. If I start weston-simple-egl it renders OK, but if I enlarge its window the output becomes corrupted, not totally, I can see the triangle is enlarged, but there is lots of random looking memory rendered as well. If shrink it back down it renders OK once it hits original size and is OK smaller. Output from kodi/mpv is also 90% junk. In the case of mpv I can reduce the vid window down in size, and when it hits the small size that simple-egl starts at it also starts to render OK. All the wayland/weston code is release. Mesa/llvm gits.

Re tested with git wayland/weston and the issue persists. Testing from mesa head R600_DEBUG=nodcc fixes. nodccclear does not fix.
I'm working on this.
This is working OK now, not sure which commit fixed it.
