It seems that EPIA's have a maximum texture size of 512 pixels. This tiny patch checks textures greater than the max supported size aren't requested.

max texture patch

I think this 'bug' is also exposed in the OpenGL transition options of MythGallery. I don't know if changing this in mythpainter is sufficient to solve this problem as well? Also: does this patch only prevent displaying textures bigger than 512 or does it (make them) scale them down as well?

No idea, although looking at the gallery opengl code it doesn't appear to adjust texture sizes to powers of 2 as required either, so unless I've missed something I can't see how it works anyway. I'll test when I'm in front of the epia.

I had indeed 'missed something'. :)

This patch also fixes the "white background" problem on my Epia. Thank you Ivor.
