lagging brush after add custom brushes

[skeh]

Hi
I'm using on tvp 11.7.4
currently i've added custom brushes through this forum
wild oil.tvpx and San_tools_BrushEraser

suddenly normal brushes has too slow and makes gap at point

even in document size is down to 480p

so i removed them on panel bar
as well as removed and installed tvp again

it still speed is slow


photoshop is great working

on m1 air

Hello, do you have a particular line smoothing setting enabled in TVPaint?
Also, does hitting "reset" on one of the default brushes make them act normal again?
