Bug ID: 94246
Summary: Text shadow is rendered incorrectly on Radeon R7 260X
Product: DRI
Version: XOrg git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/Radeon
Assignee: dri-devel at lists.freedesktop.org
Reporter: smikkelsendk at gmail.com

Log from Xorg with default options
I noticed some texts were looking blurry depending on my MATE Desktop theme and
filed a bug report to MATE team
(https://github.com/mate-desktop/mate-themes/issues/104). We discovered that
the problem is that my GFX card renders text shadows incorrectly.
Adding this option fixes the problem:
Option "ShadowPrimary" "true"
This has a side effect of disabling pageflipping. However just disabling
pageflipping alone does not fix the problem.
Also if I turn off acceleration completely with:
Option "Accel" "false"
The problem also is fixed.
Attached: Screenshot and XOrg log of when the problem appears (default options)
and when it is fixed (enabling ShadowPrimary)
