--- Comment #19 from thomas.lassdiesonnerein at gmx.de ---
Are you telling me, that the new code is better for most other users, and at
the same time works worse in my case, so you won't fix it? Then I appreciate
that you want me to understand this first and I will try now. Is the following
understanding correct?

Kernel <= 4.14: Scaling is ON by default. If users want a custom refresh rate
they would need switch scaling mode OFF via xorg.conf, but then get black bars.

Kernel > 4.14: If users want full screen instead of black bars, users have to
switch scaling mode ON via xorg.conf


Assessment:
Both are not intuitive. They relay on configuration file instead of a GUI
option in plain sight. Also: The black bars are more disturbing to the average
guy, than not to be able to set a custom refresh rate. 

Idea:
Why does the driver not Scale ON by default AND sets the refresh rate of the
preferred mode?


I know I could be completely wrong here.
