Description zerobikappa 2020-09-22 21:39:41 UTC 
SUMMARY
incorrect panel position and incorrect screen output after rotate the screen

STEPS TO REPRODUCE
1. set autohide the panel
2. run commandline `xrandr --listmonitors` and find my screen is "HDMI-0"

3. if the screen was set to landscape after reboot(see a0.jpg):
  3.1 run commandline `xrandr --output HDMI-0 --rotate left --auto` then the screen will be set to portrait.
  3.2 see a1.jpg, the panel can not show and the desktop output is incorrect.

4. if the screen was set to portrait after reboot(see b0.jpg):
  4.1 run commandline `xrandr --output HDMI-0 --rotate normal --auto` then the screen will be set to landscape.
  4.2 see b1.jpg, the position of panel is incorrect and the desktop output is incorrect.

OBSERVED RESULT
Length and width do not change after rotation.

EXPECTED RESULT
fix this issue.

update:
