I have an old Intel GMA 950 laptop used for extreme low-end testing. Using GL render-system my app crashes when I create a RTT Canvas:
Before you simply say "GMA are crap"... I've worked on a pretty complex Ogre app which uses multiple renderwindows, complex shaders and Compositors - and therefore RenderTargets, and does run on this old laptop without problems.
I will see if I can try my Canvas-based app with D3D9 render-system to see if it's GL-specific issue or not. But any clue what this error means and why it might be happening would be appreciated.
update:
So, using D3D9 rendersystem it works great. But still crashes using OGL as soon as Canvas is setup. I initially thought it might be a bad 32-bit-indexed mesh as described in this thread but I checked all my meshes are using 16-bit indexing... and anyway it works fine under D3D9.
