After updating my Ubuntu to 20.04 this night, I noticed that my IntelliJ Main menu is missing.
The Problem is exactly the same as described here: https://intellij-support.jetbrains.com/hc/en-us/community/posts/115000667510-Main-Menu-not-showing
However:
the
SHOW_MAIN_MENUoption shows no effectthe shortcut workaround is not working
the
View | Appearance: Main Menuaction is disabled:
I have tried multiple reinstalls both via snap & zipped standalone. Including purges of ~/.config/JetBrains and ~/.local/share/JetBrains without success.
