journal -b -k, the HDMI monitor fails to display after switched to mirror mode

OS: Ubuntu 18.04
Kernel: 5.3-rc3

XPS 13 7390 (TBT port) -> Dell WD19TB Thunderbolt Dock (Type C DP port) -> Type
C to HDMI(04b4:5210) -> HDMI Monitor

Toggle the display to mirror mode the HDMI monitor always get blank screen.
But after added drm.debug=0xe, it leads to this issue hard to be reproduced,
I've tried around 10 times to get one failure.
