Unfortunately there still is a problem even after applying the latest patch mentioned in: Xen-related performance problems · Issue #7404 · QubesOS/qubes-issues · GitHub
After waking up from suspend, all whonix windows are frozen in this sense: for instance with Tor Browser if I use keyboard shortcuts to move from one tab to another the title of the window changes but that’s about it, nothing else changes, the UI is frozen. I can open applications further but they’re all frozen, they accept and interact with keyboard input but graphically nothing changes aside from the first initial graphical display. And this doesn’t apply to whonix only, it also happened with a debian-11 based template but only firefox was affected, and it stayed affected even after restarting it. I don’t know what could be the cause behind this or how I can even debug it given that I can’t get any graphical update.
