This issue occurs in Iris versions 1.7.1 and 1.7.0; according to another user, it occurs in all Iris versions greater than 1.6.
GPUs where this issue is confirmed to occur are the Radeon HD 7470, 5770 (reported by @coredex-source), and 6670 (reported by a Discord user).
Shaders work as expected on Optifine, thus this issue is likely related to Iris or Sodium.
Forcing Minecraft to use OpenGL 2.0 with this mod is known to fix the issue temporarily, but also drastically drops FPS to unplayable numbers.
Two instances of this issue have been found, one with the frame C [atio6axx.dll+0x346fb0] and one with the frame C [atio6axx.dll+0x336720].
