Jittery / Stuttery / weird behavior with roto tool selected / roto brush effect applied

[Daniel Lange]

With the new "smooth" magnification introduced it completely breaks when switching to the layer window, and the roto brush tool is either just selected and or the roto brush effect is applied.

Also, magnification is not smooth on Windows

Steps to reproduce:
Select roto brush => click on footage to go into the layer => scroll with mouse.
And it's even worse when you start drawing on the layer to roto.. Magnification is completely glitchy / jittery / stuttery

Switching from Smooth to legacy kinda makes things better, but magnification takes a whole second to update..

Hi @Daniel Lange, 

Thank you for reporting this issue. Can you please share your system specs and graphics card info? 

It does look like switching to Legacy from Smooth does help a little bit but not quite all the way. 

Is the extra jitteriness happening in 25.2 or previous versions of AE? 

Thanks for your help with this,

[Daniel Lange]

Hi Dacia, problem only occurs with 25.3
Legacy makes magnification slow on my end.
