All versions of 1.7 and higher crash when using opengl

I love SCUMMVM, but I am having a real problem with all builds of version 1.7 and above. Everytime I try to run any game using the OpenGL back end SCUMMVM closes without any error messages. OpenGL works great with version 1.6 so maybe this is just a bug with the later builds. Any help would be greatly appreciated.

PC Specs:
Processor Intel(R) Core(TM) i5-4460 CPU @ 3.20GHz
Video Card NVIDIA GeForce GT 720
Memory 8.1 GB
Operating System Microsoft Windows 8 (build 9200), 64-bit

I would suggest that you get the latest code from Git and build with MinGW:
http://wiki.scummvm.org/index.php/Devel ... ng_started
http://wiki.scummvm.org/index.php/Compi ... mmVM/MinGW

Once you have done this and replicated the same crash, then run your ScummVM build with GDB and get a backtrace from the "bt" command. We can then pinpoint the cause of the issue.

Seems to be a compatibility issue with Windows 8/8.1. The following solution fixed that problem and the problem that the output in fullscreen mode is to large when using higher DPI settings:

I have selected the following options in the file properties of scummvm.exe (compatibility tab):

- Run this program in compatibility mode for: Windows 7
- Disable display scaling on high DPI settings

I hope this solution will help you too.

I'm also experiencing problems with OpenGL. The games run but the screen is blank all the time. I'm on Windows 7 32 bits.
