Created attachment 31423 [details] corruption screenshot gentoo libdrm/ddx/mesa git master with radeon rv790. kwin opengl corruptions are seen with commit 2198497203ec427f836978098028abf3350e5e57. If I move back one commit to 48dfd3938e428295c45692cfde0a2afff04a7970 no corruption is seen. Not clear on why this commit is the issue. It is wrapped in ifdef DEBUG but the gentoo mesa ebuild is setting --disable-debug. attaching corruption evidence when moving a window around.
scratch the commits above. radeon/r300: no need to flush the cmdbuf when changing scissors state in KMM mode 286bf89e5a1fc931dbf523ded861b809859485e2 is the offending commit. rolling back to the previous commit f6d0993212fac0eb67827716be1ab4a292c8b4e5 fixes it.
