Ksnip is unable to capture any screenshots.
When I select something from the New combobox,
the ksnip window quickly jumps around the screen a little
and end up in a position very close to its original position.
No screenshot is captured.
If I try to capture a rectangular area,
ksnip lets me to choose the area,
but no screenshot is captured.

Starting ksnip from the command line,
I am able to get some logs.
Apart from some warnings about missing translations,
the only log entries are one row like this
for each attempted screenshot:

Critical: Invalid reply from DBus: Screenshot is not allowed

Notes about Fedora's configuration:
The desktop environment is Gnome 41.0.
Wayland is in use.
Qt by default falls back to XWayland,
but this has been overridden in Fedora:
Qt Wayland By Default On Gnome.
However, the ksnip package reverts the override in this patch.
