Description of problem:
Installing with http://ppc.koji.fedoraproject.org/stage/21_Alpha_TC4/Server/ppc64le/iso/Fedora-Server-DVD-ppc64le-21_Alpha_TC4.iso
When navigating to the "Installation Destination" screen and there are multiple disks on the system, then, when one is selected, a large section of the screen turns black. Hitting the <Alt> key will show the text, but the screen is still corrupted.
Version-Release number of selected component (if applicable):
What version of anaconda, gtk, xvnc, etc. was this composed with? Do you have the compose logs?
Sadly no. I will ask the build team to save logs in the future.
The way I recreate what versions of packages are from http://ppc.koji.fedoraproject.org/stage/21_Alpha_TC4/Server/ppc64le/os/Packages/
Something isn't redrawing the screen right, so this is either a problem with gtk or the VNC client.
Are you still seeing this with gtk3 3.14.1 or newer ?
Yes. I am seeing it on Beta_RC1.
This is fixed in pixman-0.32.6-4.fc21
only for information:
The fix in comment 6 is a bypass, it has been validated with fc21 pre-GA TC1
The bypass avoid the problem tracked by bug 1162738.
