SUMMARY

Kolourpaint, when launched with wayland regularly, shows the desktop cursor above the paintbrush cursor, making painting awkward.

This is in Fedora 34 KDE, wayland session.

STEPS TO REPRODUCE
1. Launch Kolourpaint in KDE Plasma Wayland session
2. Notice desktop cursor overlaps paintbrush cursor
3. Launch with env QT_QPA_PLATFORM=xcb kolourpaint and the issue is gone

OBSERVED RESULT

Cursor overlaps paintbrush cursor in wayland session.

EXPECTED RESULT

Cursor to be only the paintbrush icon.

I'm also having this same issue when running Kolourpaint version 22.12.3 under wayland, the only way I've been able to resolve this cursor issue was launching with QT_QPA_PLATFORM=xcb.
