Photoshop: Freezing, and brush tool becoming weird and unresponsive

> When I restart, it’s all back to normal. OR, I will be using the brush tool, and it stops making marks. I wait, try again, and it makes a mark like I was using a mouse instead of my Wacom pen, and I was clicking to make straight brush lines. >

If it began after the update, it could be corrupt prefs or possibly that you haven't rebooted the computer. I normally don't need to do that with just an update, but the brush issue was only fixed when I did. I've used it extensively since and no repeat of that sluggish response and straight line marks. Just relaunching PS didn't help. Yes, odd.

Others besides myself have also had strange issues that cleared up when trashing prefs. So if you haven't done either, I'd suggest you rename your old Prefs (in case you can put them back in place because nothing was solved by trashing them), save any unsaved presets you've created, and try it. It may take care of this. 

And if not, come back and let us know that so far, you haven't been able to fix it.

Thanks. Save presets and trash prefs. Do you have any advice as to where I might find printed directions to do this? Seems to me that Macs hide some of these libraries. BTW, I did try rebooting. No help there.

If Google hasn't already helped—I see no one here has. The trouble with weekends.  User Library > Preferences > Adobe Photoshop CC 2018 Settings is the folder you're looking for. Apple does tend to hide the user Library. Google can tell you how to unhide it permanently, but I think Bridge doesn't hide it from you if you go to your User folder using Bridge instead of looking for it in the OS. I always add it to my Favorites panel in Bridge.

 To save yourself a lot of time setting up your preferences again, copy it to your desktop or rename it ~Adobe Photoshop CC Settings. Or put Old in front if that will make it easier to spot. Then delete the original and let Photoshop start it up. If trashing prefs doesn't help, you can move the copy back minus the tilde and overwrite the new folder.

Good luck.

Thanks for the help. I’ll give it a try... when I build up my courage. These sorts of things make me nervous. Will let you know if it works.

Howdy Edgar,

Does it ever happen when your Wacom pen is not connected?  Just trying to narrow down the trigger.

Thanks,
David
