Hello, i can't confirm this. Can you share some example file?
Also will be good if you check this in new blender.

I can't replicate Crash either.
And the @Confabulatori video doesn't show the crash, it shows the expected result.

Please try the latest daily build: https://builder.blender.org/download/

Go to File → Defaults → Load Factory Settings and then load your file to see if you still can reproduce this issue.

If the problem persists, please give us more clear instructions on how to reproduce it from scratch.

When the purple glow appears is the window closing, 3.4 is on top off 3.6.
3.4.1 is not working, 3.6 is working.
It also crashes with factory settings

As far as I know, 3.4 is no longer getting fixes.
3.3 is the last one with long term support.

This looks like a Linux-specific problem.
@lichtwerk can you check on Linux?

Like I said, it is crashing in latest main branch also with factory-startup.

I'm not able to reproduce on Linux with 3.6 or Windows with 3.6 or 3.5.

At this point since Manjaro custom builds are used (the branch: main (modified) bit), can you try with the official builds from https://builder.blender.org/download/daily/

You are right, the issue is only in 3.4.1 but not in blender-3.5.0-beta+v35.46e13cf8a529-linux.x86_64-release and not in main.
