Aseprite v1.2.10-beta2 will cause brush delay.

When I used version 1.2.9, the quick drawing was smooth.
However, there is a delay in using the pencil tool in version 1.2.10-beta2.
It may also be something wrong with my computer system, just talk about my experience.

Are you on Windows 10? is the delay present with the mouse? a wacom pencil? or the surface pencil?

I have the same problem here. Painting is lagging a little but. I’m using Win 10 pro, with both mouse and Wacom tablet.

Both the mouse and the wacom pen have a delay problem
And this phenomenon will also appear on the magic wand tool.
