as per your request as a new topic:
I have this washed out behaviour now on the Roonserver as well! Roonserver was ok with Build 521, with 528 its washed out.
Here are the driver data for the Windows 7 machine:
USER-PC Roonserver Windows 7
Intel® HD Graphics Family
1366 x 768
Bits Per Pixel
Number of Colors
Refresh Rate - Current
Refresh Rate - Maximum
Refresh Rate - Minimum
Adapter DAC Type
Running at full power
This device is working properly.
PCI bus 0, device 2, function 0
The logs I sent to you earlier.

The error seems to be in the way Roon handles the shading between black and white, as these extremes come out correctly. Many releases ago I had the impression that Roon started “enhancing” the album art, so maybe a solution would be to just make an option to override this image dsp.
