Pen input lag/stuttering after recent updates

Hi Saber team,

I’ve been experiencing noticeable performance issues with pen input in Saber that started after one of the last 1–2 updates.

Issue:
On pages that have even a small amount of handwriting or content, the canvas starts to stutter and becomes laggy when I write. Strokes feel delayed, and the pen input no longer feels smooth or responsive like before.
