Painter 2021 instability

I am using Painter 2021 and tit keeps crashing where the program either locks or just disappears in the middle of edits.

At the least it seems to put a good copy of the current project in the Recovered file location.

I am using an Alienware Aurora R7

I7 with six cores

Optane memory

64 GB of RAM

Windows 10 Home.

No Data
  • I have also been experiencing instability issues.  I have Painter 2021 installed on a 2018 15" MacBook Pro with the following configuration:


    2.9 GHz 6-Core Intel Core i9


    32 GB 2400 MHz DDR4


    Radeon Pro Vega 20 4 GB

    Intel UHD Graphics 630 1536 MB

    Here is a list of issues I had in the few days I've had Painter 2021 installed:

    1. Occasional crash on startup

    2. Not responsive after waking MBP (after going into sleep mode)

    3. After following the instructions posted here I checked "Graphics Processor (GPU)" (Corel Painter 2021 > Preferences > Performance) since it wasn't checked after running the startup's screen "Brush Benchmark test".  After testing I noticed I could no longer view videos - whether online (YouTube, Vimeo, etc.) or video files locally via QuickTime (Mp4's).

    After running a number of diagnostic tests, resetting NVRAM/PRAM and SMC, as well as starting in "safe mode" I narrowed the cause down to the Painter 2021  "Graphics Processor (GPU)" selection mentioned above.  Perhaps it corrupted a video driver file?  The only solution was to do a total system restore via Time Machine, which thankfully I had a current backup - made just a few hours prior.  Once that backup was in place the I was able to view videos once again.  Note to self: Don't ever enable "Graphics Processor (GPU)" again. :-)
