I updated mutter, disabled auto login and rebooted the system. For a couple of days I thought the click through problem was solved, but today I suddenly saw it again.
I had a maximized Slack window where the bottom left I could click through it, the upper left part did not click through. Making the window not maximized and maximized it again, now the problem is gone. I have the display scale set to 200% and have fractional scaling enabled. Also I have 2 4k monitors (laptop plus external usb-c monitor). I'm running Ubuntu24.04 which was upgraded from 23.10 etc. Running with X11. ➜ ~ sudo apt list --installed | grep mutter WARNING: apt does not have a stable CLI interface.
