Describe the bug When opening windows, they seem push each other and sometimes overlap. Windows become unresponsive. It doesn't happen 100% of the time, but almost always with video players going fullscreen and terminals.

To Reproduce Steps to reproduce the behavior: This started happening since I added a 4K monitor to my laptop. I was using a FHD monitor before and the error didn't happen.

Hey @SimonBlancoE,

Could you try enabling scale-monitor-framebuffer, logout/login and see if the situation is improved any?

See https://www.omglinux.com/how-to-enable-fractional-scaling-fedora/ for enabling in gnome.

[SimonBlancoE]

Activating fractional scaling seem to have solved all the issues.

gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']"

Thank you so much for the help and for this great extension.
