Created attachment 92240 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. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1098334 Title: [gen4 sna] Font corruption Status in X.org xf86-video-intel: In Progress Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: After enabling the SNA acceleration method and rebooting, I noticed that graphical glitches appeared in the letters on Chromium's tab bar during the mouse hover animation.
