the issue is, whenever the program either: launches window into non-primary monitor, or is moved into second monitor and interacted with, program crashes.
to explain why this is an issue, substance painter is a painting program. Digital painting uses drawing tablets. MOST people using drawing tablets professionally use visual drawing tablets, which are monitors. to that end, they will also almost always be using a computer monitor as their primary, and the tablet as a second monitor, for various reasons. this is the most common setup in my experience.
I have tried all the troubleshooting I can, and I can't get the app to remain stable if my monitor is set as primary. However if I use my tablet as a primary display, the program works as expected, without crashing, so long as I never move the window onto my monitor, which is now configured as secondary.
some suggestions from the forum had me adjust my settings through Nvidia control panel, going to 3d settings and turning off vsync, as well as setting the maximum framerate as high as possible. as far as I can tell this has done nothing, so while I think it is likely some sort of settings mismatch between the app and the monitor it is in, changing these particular settings didnt fix it unfortunately.
How to reproduce:
launch substance painter into second monitor (not primary/main in windows) or drag substance into second monitor.
right click, if it hasnt crashed yet.
it crashes.
As it is, I will just have to suffer through my drawing tablet being my primary monitor for now, hoping this post helps others with the issue get to a place where they can work, but more so I hope this helps the dev team fix the issue, as it looks like something that has been a problem for at least 3 years now. attached is my log, since I spent a bunch of time crashing the program hopefully there's at least a little bit of information there that they can use.
