Is this bug happening with both linux and windows guests? So far, I can reproduce only with current RHEL6. Can you precise the guest OS, release version, if the spice agent is running, and its version. thanks (my gut feeling is that it is a linux vdagent bug, but I need to do more research) I didn't find yet the root cause, however, I can reproduce without vdagent. It doesn't need multimonitor guest. Moving to bug QXL component (0.1.0-4.el6). Current upstream/master code doesn't exhibit the bug, however it makes Xorg consume 33% cpu constantly. I removed the edid code from RHEL 0.1.0-4.el6, it seems to help (more testing needed) Created attachment 782645 [details] Xorg.0.log (In reply to Marc-Andre Lureau from comment #2) > Is this bug happening with both linux and windows guests?

BTW, I update the spice-vdagent to the lastest version, it's hard to reproduce, but I change the resolution about 20 times, the guest start to flicker. This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux. CongDong, I can't reproduce this flickering anymore. In comment 4, I tried removing edid and it helped. Since EDID has been removed in 0.1.1, it may be the reason why this is now fixed.

Also tested with xorg-x11-drv-qxl-0.1.0-7.el6 and xorg-x11-drv-qxl-0.1.1-13.el6 Cannot reproduce with them. thanks |
