Some parts of GUI transparent

[TwistedSorrowzz]

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?

It's probably the files for the GUI, When was it made?
As it could be outdated and not work for the latest update for FH.

I'm not sure. Try to see if both of those mods have the same number of files. (If you have all the files in a folder you can always right click the folder then go to Properties to see the number of files) Maybe the Bubblegum one has some files that the Onyx one doesn't have and is causing problems.

ONYX was made for v1.15:

Oh, I used one of these interfaces before. If I'm correct only the Sapphire and another one works. Try going through the colours and see if they make any difference.

Saphire and ONYX so far don't work. I will try out others and see what happens.

[Crusoe]

Looks like none of them work for whatever reason. I recall on my other system they worked fine.

[TwistedSorrowzz]

Hmm, Well I'm sure there's an GUI like ONYX that works, You'll just have to search for it.

Or perhaps the problem is related to how the textures are exported (resolution, RGB, etc). I will take a look really quickly

[Crusoe]

Comparing two of the same images (reminder.png) in GIMP tell me that resolution (128x128), color space (RGB) and number of pixels (16384) is the same, however the color profile seems to be different.

Gemstone GUIs have a "Default RGB working space" while Bubblegum has a color profile of "IEC 61966-2.1 Default RGB colour space - sRGB."

Could this be the issue?

[Morgra]

Could very well be. I'm not 100% sure but maybe the different color profiles is what's causing your card to not render the textures.
