Disable animations during screenshots

[hattapauzi]

Summary

• temporarily disable Hyprland animations while omarchy-cmd-screenshot runs to avoid mid-transition captures
• restore the previous animation state on exit

How is the problem you're trying to solve manifesting itself? Why not just wait until whatever anim you're looking at is done?

The issue shows up when triggering the screenshot during an active animation (workspace switch or window open/close). The captured frame can be in mid‑transition, so the window appears partially offset/blurred or mid‑fade. Waiting isn’t always works out because the screenshot flow itself (slurp + wayfreeze) can be invoked while animations are still running. The change freezes a stable frame by temporarily disabling animations only for the capture, then restores them immediately after.

I could not reproduce this behavior (screenshot result that's messed up by the animation) in my other machine with the same custom animations config but the animation is still indeed rolling when invoking the omarchy-cmd-screenshot ... After applying this pull request that I did, I can confirm that the animation is not rolling therefore not messing up my screenshot anymore...

Just some example script I wrote to toggle between different scripts (some of them messed up the screenshot)

I can provide the messed up screenshot later when I got back to that machine...
