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
64 GB of RAM
Windows 10 Home.
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 https://support.corel.com/hc/en-us/articles/360025425073-Painter-2020-Tuning-GPU-settings-for-optimal-Painter-performance 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. :-)
Sorry to hear that. This may be an "Apples" and Oranges comparison (yes, pun intended). Your instability seems to be far more serious than mine. I only experience my issues when editing a fairly large image. Currently I think it may have to do with the number of layers and the file size. It only happens to me when I am moving the tool on the canvas, or so it appears to me. Moreover, I have yet to lose any files or have any system corruption. You'd think with a prodigious number of processors and a boatload of RAM it would be more stable not less.
