GTK Radiant bright UI since updating Graphics Drivers

[Hashira]

Recently installed new drivers and it has caused issues with Modview and GTK Radiant, Modview was easily fixable by installing Xycaleth's version however I am still having issues with Radiant. I have tried installing different versions but that has not worked, any help would be greatly appreciated

 

Texture Window and background are way too bright

Update/Bump: I uninstalled my drivers completely and decided to launch radiant which fixed the issue however, upon a clean install of an older Nvidia driver I now have the same issue again...

I have attempted to change colour calibration, reverted to multiple old drivers, installed different versions of GTK Radiant but the only thing that has worked has been completely uninstalling drivers with DDU. I have also found that changing Gamma in GTK Radiant from 1 to 0.5 makes everything even brighter so if there is a way to bypass the 1.0 gamma limit I wonder if that could potentially work.
Feeling quite lost here and while this doesn't exactly prevent me from making levels, it is pretty annoying to deal with. Any advice?

What versions of Radiant have you tried? Does the most recent one have the issue? I think the most recent one is 1.6.6.

I've tried 1.5, 1.6.4, 1.6.5 and 1.6.6. Same issue is apparent in each version

1.6.6 same problem
