The hang is from 10 to 20 seconds. Greatly slows things down. This is disappointing because Painter 2019 was advertised as much faster than P 2018. I am going back to using P 2018 until this is resolved as it is making P 2019 almost unusable. Running on late 2013 Mac Pro, Mojave 10.14.1. Please resolve asap, thanks.
Here is another work-around to be aware of. If this works for you, please post here!
Open your Mac system preferencesGo to "Security and Privacy"Selec the "Privacy" Tab.Go to "Accessibility"Look for Painter (in your case, Painter 2019)Uncheck Painter 2019
This should help improve performance on Mojave for 2019 and even previous versions of Painter.
Thanks very much for this. No hangs at all now. I was still getting some hangs, although they were a bit improved after updating to Mojave 10.14.4. Now there are no hangs at all. Here's something odd: after doing this work-around, the problem of jerky Liquid Ink brushes has gone away. This is not a brush I use a lot, but it is nice to have it working smoothly.
Need to clarify: The hangs were reduced under Mojave 10.14.4 but BEFORE doing the work-around. Then I applied the workaround and they went away completely. My hastily written post made it look as if hangs were still occurring after the work-around.
Sorry I didn't respond 4 months ago - got distracted with other things...
