Could you try to set the Bit Depth (Viewport) to 16 or 32?

BTW, you should disable the Debug Mode in the addon settings.

[zNightlord]

Yeah it's fixed when you change to that.

It's good to know that's the issue. Thanks!

Malt tries to find the best texture format for certain operations and that can depend on the GPU model.
The OpenGL library we use doesn't have support for some of the rarer formats, but it should be possible to find a workaround.

I'm going to keep this open so I don't forget about it.
