Title:
Multiple different display refresh rates lead to the lowest one being
chosen for rendering the window animations
Status in xorg package in Ubuntu:
New
Bug description:
I have two different monitors hooked up. One has a 60 Hz refresh rate, the
other one has a 144 Hz
one. I did make sure to select the correct resolution and refresh rate for
booth.
The issue is that any objects on the desktop environment such as
windows (browsers, file managers, terminals), basically, every
graphical part of the screen, get rendered in 60 frames per second, in
stead of the correct 144 frames per second.
This is very easily repeatable if you have two monitors with two
refresh rates, I suppose. After you set up your monitors, make sure to
enable 144 Hz, then "test" it by moving your mouse around. It should
feel smooth, just like it should on 144 Hz. Now move a window (such as
a browser, or your file manager) around. You should notice that it
still feels like it runs at 60 Hz.
To sum up:
What should happen:
- The windows that are currently on the 144 Hz Monitor should be rendered at
the specified refresh rate
What actually happens
- The refresh rate of rendered windows (excluding games) appears to be capped
to the lowest refresh rate monitor
I did test this further and it seemed to confirm my hypothesis. When I
set my second, 60 Hz monitor, to run at 30 Hz, everything excluding my
cursor was now being rendered at 30 Hz on both screens.
