Dual-Screen Files Crash Blender 2.80
Open, Waiting for Developer to ReproducePublic


System Information
Operating system: Windows-10-10.0.17763 64 Bits
Graphics card: GeForce GTX 690/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 419.35

Blender Version
Broken: version: 2.80 (sub 75), branch: master, commit date: 2019-07-29 14:47, hash: rBf6cb5f54494e
Worked: (optional)

Short description of error
Blender is not capable of opening a file with a dual-screen UI. Blender claims that the graphics card is unsupported and prompts to close the program. The same problem persists with dual-screen startup UI as well. Blender will run dual-screen UI if the file, or Blender startup, opens with only one window. "Window>New Window" while using Blender does not cause issues during use.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

I found out today that if I open blender on its own and open another window on the second screen before opening a dual-screen file, Blender does not crash.

Bastien Montagne (mont29) triaged this task as Needs Information from User priority.

Please follow our submission template and guidelines, also read these tips about bug reports, and make a complete, valid bug report, with required info, precise description of the issue (only ONE issue per report!), precise steps to reproduce it, small and simple .blend and/or other files to do so if needed, etc.

There really isn't any additional information to produce. An empty file with dual-screen UI should reproduce the problem just fine. Simply saving the default file with a second window open will replicate the issue. I know this because I had to reinstall blender because I did this and could no longer successfully open blender.

The above file had one command [Window>New Window] and was immediately saved.

Bastien Montagne (mont29) raised the priority of this task from Needs Information from User to Waiting for Developer to Reproduce.

Thanks for the file, works fine for me on linux... Might need someone to reproduce/confirm the issue on Windows?
