System Information
Windows 10
Nvidia GTX 1070
AMD Radeon HD 5570

Blender Version
2.79 rc1

Short description of error
When I start blender, in the console window it says EXCEPTION ACCESS VIOLATION and then blender doesn't bring up its windows. I keep doing it over and over and eventually blender starts. Each video card is connected to a monitor. I have blender configured for 2 monitors and 2 windows, one window on each monitor.

Exact steps for others to reproduce the error
Try starting blender.

Would suspect some driver issue… Especially mixing two cards from different makers, eeeh… Anyway, please:

Give us your exact Blender, OS and GPU (including drivers) versions, as requested in the template!
Ensure both your OS and drivers are fully up-to-date (and use official GPU drivers, not those provided by windows or tablet/laptop maker).
Try to start Blender in factory settings (--factory-startup commandline option) (this will ensure whether this is a userpref or addon issue or not).
Try to tweak your GPU driver settings (e.g. try different values between 'performance' and 'quality' if you have such slider, etc.).
Launch Blender from the command line with -d option and attach as text file here any error printed out in the console (do not paste it directly in comment).
Try to place this dll next to your blender.exe (software OGL, will be slow, but will show whether this is a driver issue or not).

I updated my video card drivers; no help from that. Here's the output with -d and your opengl32.dll. It starts with no problem with your opengl32.dll. It also starts with no problem with --factory-startup .

If it starts OK with the software OpenGL, then it means issue is with your GPU driver(s), most likely.

The other things to try (-d option, --factory-startup, etc.) are to be tried without the opengl32.dll, when this one is present it prevents any attempt to use your real GPU drivers.

I tried it with -d and with --factory-startup, without the software OpenGL. With -d it still fails, with --factory-startup it did not fail. I have very few add-ons installed but I did do some tweaking and saved a new startup file.

Thanks for your help and insights.

Closing since this isn't a bug in Blender's default setup.

If you track down the exact cause, it's worth reporting to the add-on author.

Just for the record, I turned off all add-ons, including cycles, and it still does it.

Another "just for the record" note, in case this comes up for someone else. The problem goes away when I change my startup file to have only 1 blender window (on my left AMD powered monitor). Likewise the problem goes away if I have 2 blender windows but have them both on the left monitor, and save the startup file.

can you attach your startup file that'll cause it to crash?

Rusty Wright commented

2017-08-22 21:44:29 +02:00

Argh, I can't. I swear I didn't change my startup settings except for the windows but now when I set it up with 2 windows with one on each monitor it no longer crashes. If it starts doing it again hopefully I'll remember to upload it here.
