Some parts of GUI transparent

[Crusoe]

Within the game, I have an issue with certain parts of the GUI being transparent. It seems to be a common one and the solution is to switch to DirectX, however I would prefer to use OpenGL. Any other fix besides switching renderer?

Could any of the user interface texture files have been erased by accident? Have you installed any GUI mods lately?

No. Clean install. I can reinstall it however just to make sure.

This has happened to me many times, All you need to do is download a new GUI interface.
You can find them easily on DeviantArt.

I have tried this already as well. Doesn't seem to work either. I used the ONYX one.

Reinstalling has not fixed it at all. I will try the GUI that Joji has linked.

Okay. If that doesn't work, it could possibly be a graphics driver issue. A driver could either need reinstalling or replaced.

Alright. The GUI that Joji sent seems to work, however reinstalling the ONYX GUI causes the issue again. Is the real problem the texture files of the GUI?

This is not the issue. I have just reset Windows entirely a couple of hours ago and installed the latest drivers.
