Short description of error

Blender crashes when i try to open a blend file that has any floating window open besides the main UI Window, with the following error " Blender requires a graphics driver with at list OpenGL 3.3 support "

I believe this is happening because i have my monitors plunged in to two separate video card of same make and model,

a test blend file that produces this error

I'll just throw in that if your 1080s do indeed have DVI-D output as shown in the screenshot, you can probably use a $6 DVI-D to HDMI cable to let you drive both monitors from a single card, which shouldn't be a problem for a 1080 and two HD displays.

Does it work if you only use one GPU to render opengl?

Probably a duplicate of: T61995

Yes, that seems to work, I no longer get the error when opening files with floating windows.

Thanks

While there is a workaround, we should try to fix this.

I haven't tested this setup myself, but since it's been reported by 3 users would consider it confirmed.

Can confirm that monitors should be connected to different video cards.
And using only one GPU to render opengl fix this issue.

@Clément Foucault (fclem) I think we talked about this previously. I don't think blender does anything special with multi GPU/monitor setups. So I suspect that this is an issue on the driver side of things?

If it helps i didn't face this problem in blender 2.7 ... its only on 2.8 in my case.

I will set this as a known issue. Can be how OpenGL resources are shared between the two graphic cards. Blender OpenGL assumes that there is only a single GPU to take care of.
