Ok seems we found the problem. Older machines or OS could cause the issue. We now use Qt Quick for all those nice GUI features but that causes the wallet to only work properly on OpenGL versions of 2.0 and above. See if you can upgrade your graphics driver as that solved the issue for others. You can use OpenGL Viewer to check your version

I dont know if its possible but is there anything I can install separately to help or am I out of luck?
Thanks for all your help!
