State: closed
Merged: Yes

We should be applying crop after determining the VRAM display width from GPU values rather than calculating it from the number of video clock ticks in the configurable visible display region. This is a better representation of what happens in hardware, since the GPU has no concept of what's visible or not on the user side, and is less susceptible to rounding errors than the previous method.
