<pre>I'm also affected by this character corruption bug. My hardware is a notebook
with Intel 4500M (i915 driver). First I thought it's caused by a hardware issue
with my external screen, but the notebook screen shows the currupted characters
as well. Sometimes when I scroll down to the end of a website with text and
then keep scrolling (when the end is reached), about 2 characters per sentence
are corrupted and about every 1/10 second the position of the curruptions
change. The characters that were corrupted before look fine then and different
characters are corrupted.
What I have tried so far:
- Disable/enable xcompmgr (no effect)
- Use XFCE (no effect)
- Change driver options i915_enable_rc6, i915_enable_fbc, lvds_downclock (no
effect)
- Use different fonts (no effect)
- Disable sna (works)
- Test firefox, libreoffice, chromium (all affected)
