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@lists.freedesktop.org Reporter: smikkelsendk@gmail.com
Created attachment 121882 --> https://bugs.freedesktop.org/attachment.cgi?id=121882&action=edit 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)
