    <thetext>Application: gwenview (19.04.3)

Qt Version: 5.13.0
Frameworks Version: 5.60.0
Operating System: Linux 4.19.59-1-lts x86_64
Distribution: &quot;Antergos Linux&quot;

-- Information about the crash:
- What I was doing when the application crashed:
open a JPG file: only the &quot;non-picture-part&quot; of GWenviev is rendered correctly, the picture pard is &quot;transparent&quot; shows the content of the windows behind GWenview
Double click the picture area (which is &quot;transparent&quot; as described before) goes into full screen and the picture is displayed correctly
Press Escape to get into folder view
Double click the JPG opened previously and GWenview crashes

- Unusual behavior I noticed:
GWenview on Wayland does not show the picture on first opening
Gwenview on Wayland crashes when opening the picture from the folder view

The crash can be reproduced every time.

-- Backtrace:
Application: Gwenview (gwenview), signal: Aborted
Using host libthread_db library &quot;/usr/lib/libthread_db.so.1&quot;.
