The desktop / system (and now irrelevant QT5 settings) are very like traditional Win98 / Server 2003 style, or what XP or Win7 looks like with the Eye candy turned off. All black text, white window backgrounds, grey window surrounds and traditional 3D Windows NT / Win 3.x / Win9x buttons & controls.
Is this a QT6 stupidity or a Calibre setting somewhere?
SOLUTION
I changed font to Droid Sans 10, restarted and Calibre was OK. So curious I changed it BACK to DejaVu Sans 10 and restarted and it was STILL OK!
Font now back to Black.
I'd stayed on 5.44 on my main PC and laptop rather than 6.1, 6.2. 6.3 etc because QT6 worried me. But now it seems fine.
No problem upgrading from DeDRM 7.x to NoDrm DeDrm 10.0.3

One of the differences if that QT6 has high DPI built into Qt6 and it's automatically on or off. With Qt5 you had an option. You can turn this off with an environment variable.
The second is if you are setting your display greater then 100%.
Code:
QT_ENABLE_HIGHDPI_SCALING=0
QT_SCALE_FACTOR_ROUNDING_POLICY=Round
