Description Bernie Innocenti 2021-04-15 08:09:02 UTC

Please see upstream bug for details:
https://bugs.kde.org/show_bug.cgi?id=429967

I'm still experiencing this bug in F34 on a Thinkpad with Intel graphics with:

 - gwenview-20.12.2-1.fc34.x86_64
 - kwin-5.21.4-1.fc34.x86_64
 - mesa-libGL-21.0.2-1.fc34.x86_64
 - qt5-qtbase-5.15.2-15.fc34.x86_64

obs-studio-26.1.2-3.fc34.x86_64 also shows transparent areas, not sure if same bug.
Other users report that kstars has the same problem (I haven't tested).

In case this bug affects all users with Intel GPUs, I think it should be considered a blocker for the Plasma Wayland by default feature.

Comment 1 Rex Dieter 2021-04-15 08:37:44 UTC

Not reproducible on my intel-based dell latitude

Comment 2 Neal Gompa 2021-04-15 11:08:51 UTC

I can't reproduce this either on my Slimbook with an Intel GPU.

Comment 3 Bernie Innocenti 2021-04-15 12:21:45 UTC

This is caused by a bug in the OpenGL backend. It's only triggered with a non-default config: Settings -> Image View -> Animations -> OpenGL

There's already an upstream fix:
https://invent.kde.org/graphics/gwenview/-/commit/955df5addac77b49c8349e6477806dbf27bde238

Hence, definitely not a blocker.

This message is a reminder that Fedora Linux 34 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 34 on 2022-06-07.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '34'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 34 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Comment 5 Bernie Innocenti 2022-05-13 06:47:13 UTC

This is now fixed (at least, it's fixed in F36 for me).
