Created attachment 121882 [details] 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)
