Blender Version
Broken: version: 3.0.1 Release Candidate, branch: master, commit date: 2022-01-17 12:07, hash: rB9600f36cfcba
Worked: (newest version of Blender that worked as expected)
Short description of error
[Texture paint mode lags when using a graphics tablet, not the case with a mouse.]
Exact steps for others to reproduce the error
[Create a new blender scene, delete the default cube and create a new sphere, unwrap the sphere, switch to paint mode and create a default 1024px by 1024px texture paint slot. Try texturing with a graphics tablet, and it will lag. It will not lag if texturing with a mouse]
[Based on the default startup or an attached .blend file (as simple as possible)]
Extra Information
I tried this on blender 3.0 stable, 3.01 and 3.1 alpha, same issue. There is no lag in sculpt mode, or in vertex paint, only in texture paint. The same scene in earlier versions does not lag in texture paint (any version before 3.0).
I also tried it with two different computers and 3 different graphics tablet, a Huion and a XP pen one, again same issue.
