SUMMARY
Wobbly Windows settings cause erratic behavior and lag.

STEPS TO REPRODUCE

1. Open Settings.
2. Go to Window Manager.
3. Select Desktop Effects.
4. Enable Wobbly Windows.
5. Open its settings.
6. Enable Advanced Mode.
7. Set Stiffness to 50.
8. Apply the changes.
9. Attempt to move a window.

OBSERVED RESULT

Windows move erratically and lag heavily.
The issue persists even if the Stiffness setting is reverted to normal.
Turning off Wobbly Windows temporarily resolves the problem, but re-enabling it reproduces the behavior.
The issue affects all windows and requires restarting or disabling Wobbly Windows to restore normal functionality.

EXPECTED RESULT

Smooth window movement without erratic behavior or lag.

Well that's quite wobbly indeed. :) Alas I cannot reproduce either of those issues with current git master on an AMD 760M iGPU.

Got it, thanks for testing! It looks like the issue might be specific to my hardware or configuration. Any suggestions on how I can help track this down?

You could try in the Wayland session and see if that works.

I cannot reproduce the issue either. I used the same settings as in the recording

I'll try to format this and go to another distro just to be sure but I think it's probably specific to my hardware or just corrupted.
