Brush preview is not showing. Photoshop 2020

[Luciano_Steffler]

Photoshop 2020. Windows 10.
Suddenly, the brush preview is not showing, that red mask that helps in visualizing, both the brush, eraser, stamp. It is not the CapsLook key.
I have already uninstalled the PS, reset the preferences, and nothing has resolved. Please help me!

Hi

Go into preferences and check to see if Photoshop is detecting your GPU and that OpenCL is enabled

I can't activate, But it is strange that this is the problem, because I have another computer that is working normally and its OpenGL is not activated

More than likely you have an old GPU, Photoshop version 21.2 renders some old and some not so old GPU's useless with this update.

I have reported it on the Adobe feedback forum, if it is the case that you have a older GPU then your only option is to revert back to version 21.1.3 until Adobe fix the issue

Hi

Try updating to version 21.2.1, it has fixed the issue for me, GPU is now been detected

I'm facing the same problem, I have already contacted adobe support, but so far nothing.

Not working for me either. I'm running Mac OS 10.15.7, Photoshop 22.1.0. Caps Lock is not activated.
