Yes! ... my last two sentences were about the platform-plugin. Sometimes they need some tweaking to get it right. (e.g. tegra2 has it's own mutlisampling-extension and one needs to pass special values to eglChooseConfig to get a multisampled-surfaces) That's what I meant with "is their a one" and "is the platform-plugin using it" > > Sean > > -- > Dr Sean Harmer | sean.har...@kdab.com | Senior Software Engineer > Klarälvdalens Datakonsult AB, a KDAB Group company > Tel.
