I have been trying hard to reproduce this bug, however I didn't succeed.

Can you provide the domain XML?

I realized that you have to resize window of remote-viewer (reduce or enlarge), than click into remote-viewer (do not release the mouse cursor) and move with it.

Happens on graphic card ATI FirePro V4800
Comment 7 David Blechter 2012-03-23 13:24:32 UTC 
It could not be reproduced by developer. As teh result, I low the severity and move to 6.4

Glitches on RHEL4 guest

On the client:
spice-gtk 0.11-5
virt-viewer 0.5.2-3
Comment 10 David Blechter 2012-04-25 14:21:08 UTC 
What is the use case for testing WinXP without QXL?  

Note: We are not supporting rhel4
Comment 11 Vaclav Ehrlich 2012-04-26 07:26:13 UTC 
I have Win7 guest with QXL driver. (Agent is running.)

When I resize remote-viewer window and e.g. move with any guest's window, glitches appear

virt-viewer 0.5.2-3
spice-gtk 0.11-5
Comment 12 Marian Krcmarik 2012-04-26 10:07:22 UTC 
I've reproduced with WindowsXP guest (Tools installed) on client machine with ATI FireGL V3700.

As I suggested in comment #9 Could you reproduce on client machine with a graphic card from this family?

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to

Comment 15 RHEL Program Management 2012-07-11 01:59:47 UTC 
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
Comment 16 Jérôme Glisse 2012-08-29 16:46:33 UTC 
My guess is that the issue is due to blitting from and to same surface with overlapping region, radeon driver bug. Thought that should work ok as i remember that code was tested for that...

Comment 20 Marc-Andre Lureau 2014-02-18 20:57:43 UTC 
Can somebody confirm this is ati/radeon only bug? Should this bug be moved to X/driver? thanks
Comment 21 Marc-Andre Lureau 2014-04-25 11:46:47 UTC 
closing, this is more likely an old driver bug. feel free to reopen with more details.
