Description Kamil Páral 2016-11-21 17:00:50 UTC 
Description of problem:
I'm not able to select a custom ISO in file open dialog in mediawriter 4.0.4 on Fedora 24, because the dialog does not redraw correctly. I usually see just a gray area, and sometimes I see folders, but I can't open any of them, because again I see only gray area. See attached video.

If I install qgnomeplatform (and adwaita-qt5 as a dep), the file open dialog doesn't open at all and I have to kill the app (it's frozen)

In both cases, when I (try to) open the dialog, journal prints:
Nov 21 17:57:49 titan org.gnome.Shell.desktop[1332]: Window manager warning: Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x2600007 ()

In case it's relevant, I have configured tracker to not crawl any of my directories.


Version-Release number of selected component (if applicable):
mediawriter-4.0.4-0.fc24.x86_64


How reproducible:
always

Steps to Reproduce:
1. try to select a custom iso
2. see the file open dialog gray / not working

To clarify, I'm using X11 on F24.

Comment 5 Kamil Páral 2016-11-21 17:24:30 UTC 
I can't reproduce this when I run with nomodeset (therefore forcing a fallback driver). I also don't see this in a VM. That suggests this is radeon-driver specific.

As a workaround, running this:

$ QSG_RENDER_LOOP=threaded mediawriter

causes the dialog to render fine.

Comment 7 Kamil Páral 2016-11-22 09:28:29 UTC 
I have tested this on my R9 270, and also on AMD APU with integrated R7 Kaveri graphics. Both fail with 4.0.4 and work with 4.0.5.
Comment 8 Kamil Páral 2016-11-22 11:05:44 UTC 
Since this is now fixed and only affected F25 for a short while, I'm removing CommonBugs.
