Angle with Random causes brush lag + eraser bug

[danielhalond]

When I select random to the angle of the brush it lags hard. I wonder if its possible to take a look at that. And, some large brushes from photoshop are lagging as well. I dont know why it doesnt lag in photoshop

Another bad thing is happening. When I switch from brush to eraser via shortcut (e, b) the next tool have its spacing changed. For example, sometimes (not always) when I switch from brush to an eraser the eraser gets more spacing, which it didn't have before. Same happens when I switch from eraser back to brush. Pressing quickly the resize up and resize down shorcuts seems to solve the problem temporarily

thank you
