Description Andrew C Aitchison 2012-02-28 12:37:51 UTC 
Description of problem:
oclock has problems with the SHAPE extension - 
the hands of the clock aren't visible.

Version-Release number of selected component (if applicable):
xorg-x11-server-Xorg-1.10.4-6.el6_2.1.x86_64.rpm
xorg-x11-apps-7.4-10.el6.x86_64.rpm
xorg-x11-drv-intel-2.16.0-1.el6.x86_64.rpm
 
How reproducible:
Always

Steps to Reproduce:
1. run /usr/bin/oclock
2. see a white disk with a black border, but no hands on the face of the clock
  
Actual results:
 a white disk with a black border, but no hands on the face of the clock

Expected results:
 a white disk with a black border, with black hands and a black "jewel" at "12 oclock"

Additional info:
The hands show when oclock runs on a Scientific Linux 6.2 machine and displays on an Xnest display, a Scientific Linux 5.7 or Scientific Linux 6.1 X server, but not when any version of the app displays on the SL6.2 display.

The hands also show when "oclock -noshape" is run.

This is with intel video driver - I haven't been able to test with nvidia or ATI hardware
Comment 2 Adam Jackson 2012-02-28 16:07:23 UTC 
Just to clarify, what GPU is this with?  The output of 'lspci -n -s 0:2' is sufficient.
Comment 3 Andrew C Aitchison 2012-02-28 16:43:19 UTC 
# lspci -n -s 0:2
00:02.0 0300: 8086:29a2 (rev 02)

(A Radeon X600 
01:00.0 0300: 1002:5b62
01:00.1 0380: 1002:5b72
does not show the problem, so I'm guessing it is a bug in the intel driver).
Comment 4 RHEL Program Management 2012-05-03 05:43:31 UTC 
Since RHEL 6.3 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.

example of problem without shape extension

Looks as if it is a clipping problem rather than a fault in shape extension.
Note how the square clock face is not redrawn in rows where another window overlays the clock drawn by `oclock -noshape`.
Comment 7 Andrew C Aitchison 2013-03-04 08:05:46 UTC 
The update xorg-x11-drv-intel-2.20.2-2.el6 (with kernel-2.6.32-358.0.1.el6)
seems to have solved the problem.

Closing per comment #7, thanks!
