I think I understood the issue and found a solution. It looks like many Java applcations don't work properly on a non-reparenting window manager like the one I use, but they do if you pretend to be using a reparenting one. The Arch Wiki suggests to set the _JAVA_AWT_WM_NONREPARENTING environment variable to 1 if using JRE 8, or AWT_TOOLKIT=MToolkit for a later version - but only the first one works for me, despite using JRE 17. Alternatively, wmname [2] may be used to pretend to be using a supported window manager [3]. I do not know how bad workarounds these are, though.
