SUMMARY

With animation speed set to instant, shake cursor does not work.

STEPS TO REPRODUCE
1. Set animations to instant

Cursor stays the same size

EXPECTED RESULT

Cursor to inflate when shaken

Comment 1 Parker Reed 2024-06-20 18:31:34 UTC
Subsequently the cursor size changing is entirely dependent on animation speed.

If you have it set really low, it takes a long time to inflate and deflate.
Comment 2 Nate Graham 2024-06-20 19:09:22 UTC
hah, confirmed. It's also pretty weird with the speed set to a very slow value.

Maybe we should opt this out of respecting the global animation scale.

plugins/shakecursor: Ignore animation speed

From the user perspective, shaking cursor is not perceived as an
animation, so let's ignore the global animation speed factor.
