Bug ID: 491872
Summary: Xournal++ fails to bring up its window even though the
processes are running
Classification: Plasma
Product: kwin
Version: 6.1.4
Platform: Solus
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic

SUMMARY
As mentioned in https://github.com/xournalpp/xournalpp/issues/5198
When launching xournal++ (xournalpp) no window appears, but also no error log
gets created in ~/.config/xournalpp. The app is running in the background but
no window appears. In X11 mode it runs just fine. This has been an issue for
almost a year, it has been confirmed by the app developer that it is a plasma
bug and that they don't see what they could fix on their side.
When launching through terminal I get the following:
```
xopp-Message: 10:13:58.352: TEXTDOMAINDIR = (null), Platform-specific locale

xopp-Message: 10:13:58.433: Plugin "MigrateFontSizes" UI initialized
```
And the process keeps running after that, but with no window.
If I do `xournalpp --disable-audio` the output is much shorter:
```
xopp-Message: 10:14:19.553: TEXTDOMAINDIR = (null), Platform-specific locale
dir = /usr/share/xournalpp/../locale, chosen directory =
/usr/share/xournalpp/../locale
xopp-Message: 10:14:19.561: Plugin "MigrateFontSizes" UI initialized
```
The process again keeps running, but with no window
STEPS TO REPRODUCE
1. Install xournal++ on any distribution running Plasma in Wayland mode
2. Run xournal++ from the shortcut or terminal, no window will appear
3. Run `xournalpp --disable-audio` - same result
4. Run the app in X11 mode `GDK_BACKEND=x11 xournalpp` - the app launches just
fine
OBSERVED RESULT
On plasma the app only runs in X11 mode
