BSL not working correctly
This happened and still persists through multiple versions of BSL (8.2.09p2 and 8.2.09p2) and Iris (1.7 and 1.6.17).
This initially happened as I tried to use Vivecraft with Distant Horizons and the DH-Chunks just did not show up. According to some Posts, using Shaders fixes this, and Bliss as well as Photon did, but had weird issues with incorrect positions of the right and left eye, and BSL did this.
I have an AMD GPU with Mesa 24.1.0 on Gentoo Linux

Solution
Seems to work fine with Complementary Unbound although it is capped at 45 fps...
