What happened?

So Idk why i never noticed this cause i swear it worked before. But the scopes of Crayfishs guns have this weird "thermal" look to them. now i have encountered this on both 1.18.2 and 1.19.2 with Various versions of Both Oculus and Rubidium.
And it looks like its not an Issue that came up all off a sudden with an update unlike i originally belived.
Its only with shaders (any form what ive expirienced) so i guess its an issue on Oculus/Iris end.
To reproduce simply:
Install Grayfishs Gun mod + Oculus.
Place a scope with zoom (either Medium or Long) on the Gun via the Attachment menu.
And activate a shader.
Now aim.

Screenshots

I used Complementary shaders 4.6 in this example but it happen with Sildurs etc. too.

If there is anything else i can do tell me.
And yes its not a general shader issue with Grayfishs Guns mod, it workes fine with Optifine.
I just wrote the versions of the 1.19.2 MC version since its the newer version and the one where i originally found the bug.
I hope its a thing u can fix i also reported this to Mr Crayfish just incase.
Would be a shame to trade the Pros of this back for Optifine.
