Mixer brush causes PS to freeze up.

[CandaceB832]

I have PS2021 and when I use my mixer brushes, PS freezes and I have to go to the task manager and shut it down.

Hi

Are you on a Mac or a Windows Machine? Maybe a Graphic-Card-Driver or corrupt Brush?

You can try to reset Photoshop by…

• Press Ctrl-K (PC) or cmd-K (Mac).
• Click on "Reset Preferences on Quit" in the "General" tab and press OK to confirm.
• Press OK to close the Preferences window.
• Restart Photoshop.

or…… it could be an old/outdated Plugin/Extension:

Good luck.
