I attached a GIF below demonstrating the problem: the inversion appears to do something but the result is an extremely bright, mostly white display.

The inversion is done via `xcalib: `
graphics card:
This is on debian bookworm and xcalib 0.8
Color inversion works normally from a different machine using the same monitor, same OS, same xcalib version but different graphics card:
The inversion is done via `xcalib: `
