$ rendercheck -t fill,dcoords,scoords,mcoords,tscoords,tmcoords,blend,composite
-f a8r8g8b8,x8r8g8b8,a8

results in 2024854 tests passed of 2124238 total with 99384 failing

Version-Release number of selected component (if applicable):
xorg-x11-drv-intel-2.16.0-1.el6.x86_64

How reproducible:
Run the command above

Actual results:
See the log

Expected results:

Comment 3 Adam Jackson 2011-10-11 13:28:04 UTC 
Summarized results (count of failed tests per op, name of blend op):

% grep error rendercheck-irl | awk '{ print $1 }' | sort | uniq -c
9920 ConjointAtop
8968 ConjointAtopReverse
9000 ConjointDst
9000 ConjointIn
8968 ConjointInReverse
2240 ConjointOutReverse
9920 ConjointOver
9000 ConjointOverReverse
9000 ConjointSrc
2240 ConjointXor
9920 DisjointAtop
8968 DisjointAtopReverse
2240 DisjointXor

The conjoint and disjoint ops are virtually unused (and were something of a mistake in the first place).  For future rendercheck runs they can be skipped by invoking rendercheck with:

-o clear,src,dst,over,overreverse,in,inreverse,out,outreverse,atop,atopreverse,xor,add,saturate

Moving to 6.3.
Comment 4 Tomas Pelka 2011-11-02 12:52:42 UTC 
I think this issue similarly as other rendercheck bugs are caused by running gnome-screensaver. I mean when g-s lock the screen during the test.

Without g-s it will PASS.
Comment 5 Adam Jackson 2011-12-15 20:22:43 UTC 
Closing per comment #4, test environment needs to suppress the screensaver.
