Comment 5 for bug 1971693

The bot strongly recommends to set package for the bug, but I have no idea at the moment where the problem is exactly. This is definitely not a Java bug, my best guess is that it's a recent problem in mutter Wayland compositor, so I'll pick that. But this just as well might be e.g. an XWayland issue.
If anyone knows better, please update the package field, or let me know if I should update it.
