Description Lubos Kocman 2011-07-26 11:46:05 UTC

Description of problem:

If you'll start spicec with fullscreen option then Xorg on a RHEL 6 client is completely messed and you need to switch to console and back to Xorg to get it redraw correctly.

This happens also when you're switching from window mode to fullscreen mode.

This does not happen with windows guest. Seems to be RHEL6  guest specific.


Version-Release number of selected component (if applicable):

spice-client-0.8.0-2.el6.x86_64
xorg-x11-drv-qxl-0.0.12-2.1.el6_0.1.x86_64
xorg-x11-drv-intel-2.14.0-1.el6.x86_64
spice-vdagent-0.8.1-1.el6.x86_64
qemu-kvm-0.12.1.2-2.171.el6.x86_64

How reproducible:

start rhel6 guest

Steps to Reproduce:
1. connect using any way to the guest
2. switch to fullscreen (does not matter if it's with spicec -f or later by using shift+f11)

  
Actual results:

nothing is readable on the screen artefacts are all arround, even after closing spicec

Workaround: switch to console and then back to X

Expected results:

No artefacts should appear

Additional info:

Nothing special in spicec log
Reproducible always on my setup (just with one monitor)

No qxl device ?

Comment 7 Lubos Kocman 2011-07-27 10:17:15 UTC

Switching spice-client forces client to change resolution, so the real problem is really just changing resolution on mentioned intel gpu. 

Reproducer:

xrandr -s RESOLUTION_MODE

I've tried few builds back but I felt into several issues:

xorg-x11-drv-intel-2.15.0-2.el6 (reported against)
xorg-x11-drv-intel-2.15.0-1.el6 (same issue)
xorg-x11-drv-intel-2.14.0-1.el6 (does not recognize multiple displays and allows only 1440x900)
xorg-x11-drv-intel-2.11.0-7.el6 (same as 2.14.0-1)
xorg-x11-drv-intel-2.11.0-6.el6 (same as 2.14.0-1)

Hope that it will give you any ideas. (This issue happens for not more than one month). Wasn't there any big change in Xorg or in glibc that could cause it?

Comment 11 Lubos Kocman 2011-08-03 11:36:36 UTC

Seems like issue got fixed by update:

of xorg-x11-drv-intel-2.15.0-2.el6.x86_64 or kernel-2.6.32-174.el6.x86_64

Closing as current release.

Feel free to open bug if the issue occurs again.
