- In plugins that have adjustment wheels, it seems that the wheel's indicator needle isn't centered but is shifted to the lower right. As a result, the needle appears smaller and moves in a “strange” way.
Speaking of plugins: it wouldn't be a bad idea to include a “reset” button in every native plugin.

- Running both the AppImage and the build with the environment variable `QT_QPA_PLATFORM=wayland` always results in an X11 environment:

cin: display platform xcb (X11 display)

The same thing happens with the two AppImages, including the one for older systems.
I use Arch Linux, KDE Plasma (Wayland). It's probably just an issue with my system, since it works fine for Terje.

- With the AppImage for older systems, I don't encounter any of the issues IgorBeg found; perhaps there are still some external libraries that aren't working? At startup, I only get a few warnings about fontconfig, but they don't affect CinGG's operation. With the other AppImage and with the build, I don't get these warnings.
