* Another workaround for NVIDIA driver 496.13 shader bug

This might work better than the other one. Give this a test to see if it fixes/doesn't fix issues with the other one.

The problem seems to be when any variable assignment happens with a negation. `temp_1 = -temp_0;` seems to trigger weird behaviour, but `temp_1 = 0.0 - temp_0;` does not. This also might to extend towards integer types?

* Update cache version

* Add disclaimer comment

* Wording
