Description Pierre Ossman 2005-09-29 01:02:34 UTC
There are slight graphical bugs around glyphs with EXA acceleration. Problem is
not common and seems to get more frequent in areas close to the mouse pointer (hw).

CVS snapshot from 2005-09-28. Card is Radeon Mobility 9200.

Bug only seems to appear when using subpixel anti-aliasing.
Comment 4 Adam Jackson 2005-11-30 16:34:27 UTC
not a blocker, as exa is experimental.  will still take patches for it of course.
Comment 5 Eric Anholt 2006-04-02 14:24:18 UTC
If you could retest with current ATI driver, and X Server as of today, I've
fixed many issues that could relate to rendering problems like this.
Comment 6 Pierre Ossman 2006-04-02 20:54:14 UTC
Just the Xorg server and ati driver? I don't want to compile more than necessary
now that we have this new shiny modular structure. ;)
Comment 7 Eric Anholt 2006-04-07 14:20:30 UTC
The other new dependencies will be whined about during ./configure of the X Server
Comment 8 Pierre Ossman 2006-04-11 03:14:07 UTC
Sorry this took so long. I've tried with the current version of the server and
ati driver and I can no longer reproduce the glitch. Great work! :)

marking as fixed according to the reporter.
