Jump Desktop now tries it's best to accurately reproduce colours. This means that videos and images you see on your local monitor will now be much closer to how they're supposed to look.
Jump does this by doing two colour conversions: It first converts colours to a neutral colour space on the host machine and then does one more conversion to map colours to your local monitor's colour space. The final result is colours looking like much better overall.
This feature requires Jump Desktop Connect 6.7.42 or later on the remote machine.
