Fixed in sna. This is one of the areas in UXA that can just die... Just use SNA already ;-) I've still no intention of rewriting UXA in the same manner as SNA to avoid this mistake (because people will still complain about the radical changes required), however Julien didn't like this bug being closed with "use sna" so make UXA fallback rather than fail. commit 5c45622b889ba66b6476241601e1458d219c45ba Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sun Oct 30 17:49:19 2011 +0000 uxa/glyphs: Fallback rather than fail to render with a non-solid Source Reported-by: Uli Schlachter <psychon@znc.in> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=31819 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> |

Created attachment 40456 [details] Test case Hi, I took a closer look at the results of cairo's test suite results when run against Xvfb vs my intel graphics card and noticed that there are a couple of tests where text is missing. I came up with a cairo-free test case (attached). It can be compiled with g++ -o missing_text missing_text.c `pkg-config --cflags --libs xrender` I am using debian testing's xserver-xorg-video-intel 2:2.13.0-2. When run against Xephyr, a window with a linear gradient is displayed. Running it against my X server results in a black rectangle where the glyph should be. From cairo's test suite's result I'd guess that the same happens with other types of source images, but I haven't verified this with a test case yet. Cheers, Uli
