Bug ID: 468776
Summary: Multiple Applications not showing any content, for
some hardware
Classification: I don't know
Product: kde
Version: unspecified
Platform: Neon
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: pasdabonneme...@gmail.com
Target Milestone: ---
SUMMARY
They are multiple applications which are not showing their content anymore, on
both Wayland and Xorg (X11). On wayland it is just black, and on X11 we see
what was behind the window when it has open itself.
It is not the case for many applications, just for some of them. And it is also
the case for some stuff (pop up, menu) appearing on top of applications.
It seems related to some hardware, as this bug appear on my tower and not on
two laptop (all running the same OS with the same version).
It's like that since something like a week.
EXAMPLES CASES
This bug appear on the full window of Discord and Spotify (both using
Flatpack).
It appear on all the menu of Brave (Flatpack) but not his window itself.
I don't know if it is related but the Firefox version distributed by "KDE neon"
also doesn't work and is completely purple (not the same behaviour so it
doesn't seem to be the same issue).
The Flatpack version of Firefox has not any issue.
LibreOffice is affected differently, so maybe his bug is not related. It
doesn't work on X11, still showing a bit of text where other application don't
show anything. And it work fine on wayland.
The bug doesn't appear on most app : System setting, Discover, Firefox
flatpack, VLC ...
STEPS TO REPRODUCE
1. On a computer (hardware) affected with the bug, Just open an Application
affected by the bug (like Discord).
2. See that the content doesn't show up anymore.
OBSERVED RESULT
On wayland the window of an affected application is just black.
On X11 the window of an affected application show what was behind the window
when it has open itself.
When moving the mouse over the application, the cursor can change depending of
where it is, like if the content of the window was still here.
See pictures for how it looks like.
EXPECTED RESULT
We should be able to see the ordinary content of each application.
