Created attachment 1529134 [details] gnome-shell backtrace Description of problem: After resume (mostly the second time) I end up with blank screen and cannot switch to VT. Remote login to the machine shows gnome-shell process (user session and gdm session) are eating 100% CPU. From the backtrace it looks like deadlock. Both gdm and user sessions are Wayland. The attached backtrace is from machine with NVidia GPU using the binary driver but I was able to reproduce this also on my laptop with intel gpu. It's a regression as this didn't happened before in rhel8 I suspect it happened after mutter-3.28.3-11.el8, but I have to retest to be sure. Version-Release number of selected component (if applicable): gnome-shell-3.28.3-9.el8 mutter-3.28.3-16.el8 How reproducible: 100% Steps to Reproduce: 1. Login to gnome session 2. Suspend/Resume 3. Suspend/Resume Actual results: deadlock Expected results: The resume is successful Additional info:
