Image showing the artifact on a firefox page
Just a short note to report that after a period where these were not evident, I
am again experiencing important rendering issues on gen4 graphics card.
Some details:
Hardware DELL E6500
OS: kubuntu 13.04 + kernel updated to 3.9.5 via ubuntu mainline ppa
Graphics stack:
xorg core 1.13.3
xserver xorg video intel driver 2.21.9+
(git snapshot taken 13-06-11 - b9439a...)
libdrm 2.4.45+
(git snapshot taken 13-06-07 - a0178c...)
mesa 9.2+
(git snapshot taken 13-06-11 - 761320...)
The artifacts are particularly evident in
- firefox (see attachment)
- libreoffice
In both cases the artifacts affect not just what is rendered, but also the
thumbnails created by the application (those in firefox start page and slide
and drawing thumbnails in libreoffice impress/draw).
Artifacts interest squared chunks on the screen where patterns appear instead
of images.</pre>
