Description Bojan Smojver 2015-11-03 03:42:50 UTC

Description of problem:
Upgraded an F-22 i686 VM to F-23 using dnf. I can see the desktop and start the apps, but redrawing has all gone nuts. Artefacts of previous windows, even the overview mode (i.e. dash etc.) are appearing as the mouse is moved around. Eventually, the text editing cursor appears and the session locks up. 

Version-Release number of selected component (if applicable):
gnome-shell-3.18.1-1

How reproducible:
Always.

Steps to Reproduce:
1. Start an xrdp/vnc session with vnc backend.
2. Run Gnome.
3. Pain. :-(

Actual results:
Redrawing madness.

Expected results:
Works fine in F-22.

Additional info:
Downgrading to F-22 now.

Comment 1 Bojan Smojver 2015-11-03 04:38:49 UTC

As expected, downgrading the VM to F-22 makes everything sane again.

Comment 2 Bojan Smojver 2015-11-06 00:06:38 UTC

Running 16-bit colour depth, to reduce bandwidth requirements, if it matters.

Might be a duplicate of bug 1279146

Comment 4 Sylvain Pasche 2015-11-19 16:27:23 UTC

... or not. Are you using tigervnc?

xrdp uses tigervnc in the back end. So, yeah, could be a duplicate.

Comment 6 Bojan Smojver 2015-11-20 03:23:08 UTC

Yeah, build -4 is the fix for this one (rendering for sure, not quite sure on crashing yet - too early to tell).
