An internal OpenGL call failed...

[texus]

I haven't been immediately able to reprocude the error (MinGW 4.7.1 TDM).

Maybe it happens on specific code? Could you show some minimal code to reproduce this?
Maybe by placing some couts in your code you can find out where the error happens?

PS: You switched the sfml and tgui commit numbers.

I try to make more minimal code later, but here is the code what i have now: https://github.com/CoreTec/GraphicSystem
In GraphicSystem all init things happens. In GraphicSystemTest i draw TGUI example with GraphicSystem.

I have been able to reproduce the error now (based on what you had in GraphicsSystemTest), so a minimal example isn't needed anymore.

I'll see if I can find the issue.
The errors only started after loading a font, so I already know where to start looking.

I downloaded the v0.6 Release Candidate Pre-compiled Binaries for Visual Studio 2012 32 bits, and there is a similar issue. I created the gui, loaded the font, and made two edit boxes. When I try to draw the gui

An internal OpenGL call failed in RenderTarget.cpp (61) : GL_INVALID_VALUE, a numeric argument is out of range

Is printed to the console.

Could you try with the beta version? (http://tgui.eu/wp-content/uploads/2013/03/TGUI-0.6-beta-Visual-C++11-2012-32-bits.zip)
If that version is working then something went wrong afterwards.

If you have a lot of time then you can try with different version that you compile yourself, to locate the commit where it went wrong.
Otherwise you'll have to wait until I find time to test this what is going wrong. And I don't have much time right now.

Can you send me the exact code that I need to reproduce this?

Do you only receive this error with edit boxes, or also with other widgets? If you also get it with other widgets, do you also get it when drawing images and text directly with sfml?
Do you still get the error when not loading a font?
