SUMMARY Whenever I leave my pc to automatically lock and turn off the screen, after waking up, both of my monitors are completely frozen and after a 10 to 20 seconds it fixes, you can also switch ttys to fix. I can also log in and when the screen fixes I would be logged in, so only the screen is frozen. This seems to be only a issue with x11 STEPS TO REPRODUCE 1. While unlocked wait for the monitor to turn off, without it being locked before turning off the screen 2. Wake up OBSERVED RESULT Freeze on screen EXPECTED RESULT SOFTWARE/OS VERSIONS Kernel: 6.11.2-zen1-1-zen (64-bit) KDE Plasma Version: 6.2.0 KDE Frameworks Version: 6.6.0 Qt Version: 6.7.3 ADDITIONAL INFORMATION I have reinstalled my pc and the issue still persisted, I'm with a nvidia gpu, which is the main reason I do not use wayland.
Does it happen with: 1. Only one screen? 2. Not using screen locking, and only letting the monitor(s) go to sleep? 3. Not letting the monitor(s) go to sleep and only locking and unlocking the screen? Basically, let's try to narrow down the exact event that causes this. Thanks!

Issue persists with only 1 screen (I disabled the second screen through settings) 2. There is still freezing even without screen locking 3. Locking and unlocking does not cause freezing My guess is it's the screen sleeping that is bugged

Also no issues when locking before screen sleeps.

Update: I guessed that sleeping the monitor before locking fixes it (may have been a fluke), but it doesn't, so only thing that fixes it is first locking then sleeping.
This happens on my screen with no locking enabled. There is a freeze for about 20 sec before things start functioning again. This was not the case in the past (a few months ago). I am on Fedora 40 with daily updates and using Plasma X11. Kernel: 6.11.4 KDE Plasma Version: 6.2.1 (and 6.2.1.1 for kwin and workspace) KDE Frameworks Version: 6.7.0 Qt Version: 6.7.2
