Reproduce steps: ---------------- 1. start X 2. compile and run attached test case Current result: ---------------- alpha component is not correct.

this issue does not happen in DRI mode anymore. and seems this issue is blocked by and quite related to bug #14271
Seems OK in core Mesa with Xlib driver if you 'export MESA_GLX_FORCE_ALPHA=1'
