Short description of error
When painting textures in 3D viewport brush lags very much, so that it is not even possible to draw a circle. In Texture editor it works fine.

Exact steps for others to reproduce the error
The same issue with any mesh. Does not matter how many polygons. increased brush spacing also does not help.
Attaching short video with this issue.

I also noticed, that if the brush size is much smaller, then the issue disappears, or even with larger brush the lag is not so bad. the worst lag is with medium size brush..
