setting.json was an idea, but if its deletion doesn't change anything, it's not that.
I suppose the bug happens even with a new project?
Which version do you use? I'm going to try a quick fix but I'm not sure that that solves the problem...
Hi, here is an attempt to fix it: https://framadrop.org/r/Ow4Xg909c4#1PRrWInaRR24oDG0egaTHu0mN/n2SphNyNFZGGWukUI=
Can you try it and tell me if it solves the problem for the palette window or for all windows or for none?
If none, you can try to press f12 with the focus on the main window (the one with the menus) and see if there are any error messages in the console....
