Description Fushan Wen 2022-02-17 09:16:08 UTC 
SUMMARY
If I turn off the screen for a while and turn on the screen, only the desktop will respond the touch events, the panel doesn't, and the window in the foreground doesn't accept touch events either and will forward all touch events to the desktop.

STEPS TO REPRODUCE
1. Turn off the screen for a while
2. Turn on the screen
3. Touch on the screen

OBSERVED RESULT
The debug console said there were touch input events, but only the desktop can respond to them.

EXPECTED RESULT
Normal behavior
