Short description of error
Lags when brushes size change.

Exact steps for others to reproduce the error

  1. Please open the attached file.
  2. Please Sculpt ( clay strips already active ) on the model about 2 time.
  3. Press F and change brush size . ( lag about 1 sec)
  4. But can change the brush sizes without any lag after that.

5.Then sculpt about 2 times on model
6.Then press F and change brush size --- lag again.

  1. Many brushes have similar error.

8.Blender 2.8 had no similar error.

  1. I used Dyntopo with brush detials. Other sculpting experience is very good. Amazing. Much better than Zbrush Sculptris mode.

Attached Blender file.
