Text with errors
Recently I'm noticing somewhat more 'weird' behavior - it might be related to my temporal usage of night releases of Mozilla (since rawhide version got somewhat broken)
What is weird in this image is - the text was badly rendered AND it remained visible even when refreshed, even small scroll up/down left the text as is - it helped only to scroll text out of window and back.
So I assume now the rendering happens to some off-screen memory - which is then transfered back to screen with errors - and refresh doesn't help with this case.
(and it's a bit different then during typing text into input box).
Another probably unrelated comment could be - even when 'glxgears' is running in parallel - the visual errors still happens during typing of this text. I'd have expect the glxgears manages to 'overfill' GPU queue (since it's rendering ~1300FPS with default window) also the flushes are probably completely different. And - there is no observable rendering error in gears window - only Firefox seems to be exposing them.
