Not an expert on the subject, but AFAIK Jetbrains runs their own Java VM by default.

To run intellij on Wayland you do need _JAVA_AWT_WM_NONREPARENTING=1 in your env. It works, but has some quirks as I wrote above.

Sorry, that's not true. This just makes it "work", but it's still being rendered in Xwayland.

Here's how you can test:

Run intellij; `pkill Xwayland`

or, try running intellij on a machine which does not have xwayland installed at all.

The thing is: wayland does _not_ have scaling issues, those are inherently X11 problems.

The issue which is tracking this: https://youtrack.jetbrains.com/issue/JBR-3206

I also just ran this and watched for Xwayland to spawn, killed Xwayland and it died.

Looks like you are right, I didn't realize that Xwayland was still used in the background.
