Description

After updating, it seems that the default for explicit sync has been changed to on by default. This seems to cause a weird freezing issue on at least nvidia gpu's while using the 560.31.02 driver with the open kernel module. The screen i had focus on would freeze after 10 - 20 seconds of focus, and moving to another screen with the mouse or shortcuts did still work, until all my screens froze. This caused hyprland to crash. Disabling render:explicit_sync seems to fix this issue.

I think this is just an issue with the Nvidia driver not properly supporting explicit sync for wayland yet, so for now I'd see this more as a bug report for people who run into this issue to quickly be able to find what can fix the issue for them

How to reproduce

have an NVIDIA gpu with the NVIDIA 560.31.02 driver (may also be the case with older driver versions) and the open kernel modules (did not test with the "old" closed source kernel modules).
Once loaded, your focused screen will freeze after a little bit, but you can still move your mouse if you have another screen
After all screens are frozen, hyprland will crash to the TTY (I do have SDDM, but it did not go to SDDM, which it does do when i normally have a hyprland crash)

Crash reports, logs, images, videos

seems like there is no crash report of this, if needed I will try and get it to generate.

From the release notes:

Explicit sync support has been added and will be automatically turned on/off depending on your setup. For some select nvidia users, this might cause glitches. In such cases, disable it with render:explicit_sync = false

So this is more or less expected, for context: #7151

seems i've missed that, i'll close the ticket, just wondering what causes certain nvidia users to have the issue while others don't

thats an nvidia bug fwiw
