One interesting observation is that your logs are saying that 60Hz is
the preferred native mode of the monitor:
[ 1165.229] (II) modeset(0): First detailed timing is preferred mode
[ 1165.229] (II) modeset(0): Preferred mode is native pixel format and refresh
rate
...
[ 1165.229] (II) modeset(0): Printing probed modes for output DP-1
[ 1165.229] (II) modeset(0): Modeline "1920x1080"x60.0 148.50 1920 2008 2052
2200 1080 1084 1089 1125 +hsync +vsync (67.5 kHz eP)
[ 1165.229] (II) modeset(0): Modeline "1920x1080"x144.0 356.39 1920 2008
2052 2200 1080 1084 1089 1125 +hsync +vsync (162.0 kHz e)
[ 1165.229] (II) modeset(0): Modeline "1920x1080"x120.0 297.00 1920 1968
2000 2200 1080 1083 1088 1125 +hsync +vsync (135.0 kHz e)
...
Which is also shown in this list:
1920x1080 (0x48) 148.500MHz +HSync +VSync *current +preferred
h: width 1920 start 2008 end 2052 total 2200 skew 0 clock 67.50KHz
v: height 1080 start 1084 end 1089 total 1125 clock 60.00Hz
1920x1080 (0x49) 356.390MHz +HSync +VSync
h: width 1920 start 2008 end 2052 total 2200 skew 0 clock 162.00KHz
v: height 1080 start 1084 end 1089 total 1125 clock 144.00Hz
1920x1080 (0x4a) 297.000MHz +HSync +VSync
h: width 1920 start 1968 end 2000 total 2200 skew 0 clock 135.00KHz
v: height 1080 start 1083 end 1088 total 1125 clock 120.00Hz
So it sounds like this might be a hardware limitation. Maybe it's
changing something unusual to go above 60Hz and maybe just the Windows
10 driver is better at handling that, whatever it is.
If this is a software bug then it should probably be assigned to the
Linux kernel or Xorg modeset driver. Because the details of the pixel
layout are only known and controllable there.
** Package changed: gnome-shell (Ubuntu) => linux (Ubuntu)
