[radeonsi] Rendering of Firefox UI and website content corrupts randomly and after window geometry changes
With recent mesa git-master, often this corruption issues occurs when changing window geometry of Firefox 88 beta 7 (Webrender enabled, GLX backend, with and without window compositing), or sometimes also when just opening new websites etc.:
I suspect this happens since the latest barrage of optimizations for RadeonSI, i.e. ac78b12e and subsequent commits. Doesn't occur with 688dada1 .
