Cause:
In some circumstances (non-RGB images with no pallete and with masks), images were not used.
Consequence:
Some images were mis-rendered, such as icons with a black background or white rounded corners
Fix:
Render such images instead of dropping them
Result:
Rendering looks better.

winxp icon background
note also the white background of "ca.crt" desktop icon

winxp icon background
note that when selected, the tranparency of "ca.crt" icon works just fine
I forgot to write to the description this: the issue is not present in spice-server 0.10
The bug only shows up for "-M rhel6.3.0" or lower, when using "-M rhel6.4.0", it isn't there. Could this suggest bug in qxl device? BTW bug 886125 reproducibility also depends on qemu machine type. Host software versions: spice-server-0.12.0-8.el6.x86_64 qemu-kvm-0.12.1.2-2.340.el6.x86_64 seabios-0.6.1.2-25.el6.x86_64 vgabios-0.6b-3.7.el6.noarch in F18, the bug is gone now.

BTW bug > 886125 reproducibility also depends on qemu machine type. Could also be a guest driver bug. rhel 6.4 adds new spice capabilities which indeed affect transparency rendering. Those are turned off for compatibility reasons when running with the 6.3 machine type. So it could be the new guest drivers have trouble handling the old qxl device correctly. The fact that with F18 the bug disappeared (did you update the guest driver?) suggests that it actually is a guest bug. Do the guests with the new qxl driver show idendical behavior RHEL-6.3 and on RHEL-6.4 when starting qemu with -M rhel6.3.0 ? Created attachment 662350 [details]
fix for the windows guest issue
I think that the Linux guest issue results from a different bug than the Windows guest one.
A patch for fixing the Windows guest related bug has been posted (attached).
David, can you open an additional bug for distinguishing the 2 cases?

I couldn't try that because when I'm working with more VM's, I'm experiencing total host freeze... :( (In reply to comment #6) ... > David, can you open an additional bug for distinguishing the 2 cases? I will if I see the bug in Fedora again. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
