When using Awesome WM, Intellij main menu is broken. It's either immediately closing after opening. Holding the mouse button keeps the menu open, but I can't select anything. Sometimes the menu opening works, but the mouse cursor position is off. The selected item is approxmately one line below my mouse cursor.
I tried the recommended wmname LG3D fix, but it doesn't work.
wmname mutter helps sometimes. If the menu is working, the mouse cursor position is correct. After some time the menu bugs out still and immediatly closes after clicking.
I think it's weird that I got these problem, as awesome is supposed to be a re-parenting wm now. FWIW, in i3-wm I didn't notice this bug.
