I have come across a problem with 2D OpenGL rendering. When I use the built-in graphics chip on my Windows 7 PC (Intel HD Graphics P4600), OpenGL renders some very strange results. I have replicated this with the Juce Demo, where 2D rending fails (see the attached image) but 3D rendering is completely fine.
I have checked on another machine running an Intel HD 4600 (not P4600...) and the problem is not present, so I suspect it is something specific with this chip.
I have checked and can render OpenGL graphics using other software, it only seems to be Juce which is effected.
Any help would be appriciated.
