I'm getting this bug when using complementary shaders on 1.7.0
When the bug occurs, changing or turning off shaders doesn't undo it. Neither does reloading the world. Reloading the client does help.

It seems that it is dependent on the item that is current being held. Some items never trigger it like my tinkers tools. Some items trigger is sometimes like my forestry backpacks or the hang glider as shown in the screenshot. Sometimes I get a weird screen (see screenshot). Sometimes I just crash. I haven't been able to find a crash log however, with the mc log in Prism just saying "exited with code ..." (see log). Changing shader settings hasn't worked. BSL didn't seem to trigger the bug at first but then it did. Tea shaders also trigger it.

PS: I'm a programmer and would like to solve this bug myself as I would really like to use the complementary shaders. If someone could inform me or point me to a resource on how to get started with this, I would appreciate it.

Additional info:
I have an AMD graphics card. This has caused strange problems before.
I can easily reproduce this bug by installing a new instance, creating a new world, enabling shaders and opening inventory while holding a hang glider.

Expanding on this, it seems like things that brighten the inventory (like flint) also cause fog to appear? Also, some items such as redstone dust darken the inventory (and don't result in fog). Running Complementary Unbound 5.3 on medium settings on GTNH 2.7.0.

Edit: After restarting my computer, the aforementioned items no longer cause any visual effect.
