Black Boxes, Exported Images With Text II

Could be, or it’s more specifically an OpenGL issue within SketchUp’s code.

… and if so, you’ll never realize the benefits of overhauls that come with newer versions.

I would try checking the “Use maximum texture size” option.
(Without the box checked, I’d think some limitation would be active.)

Then try with better anti-aliasing settings.
(Looks like you have it set for no anti-aliasing, [0x].)

Also, try with and without Fast feedback (as a last resort.)

EDIT(Add): I see in the other thread that you already tried both Fast feedback settings.
