[Incompatibility] ComputerCraft monitors to appear darker

[hugeblank]

What happened?

The latest version of Iris (1.6.1) causes monitors to appear darker than they are without Iris. This issue occurs even when shaders are disabled. In 1.6.0 the issue is no longer there.

The issue is still present in v1.6.3.
Monitors appear darker only when shaders are disabled.
