[plasmashell] [Bug 410889] Panel flickers when showing the panel initially after showing an auto-hidden panel on the left edge

--- Comment #1 from Thomas DeRensis  ---
I believe I have found the cause for this issue. I had a Touch Action enabled
for the left edge (Toggle Window Switching). If I disable this, then the visual
bug goes away. This solves my issue because I don't need that touch action
enabled.

Demonstration of the panel flicker bug

SUMMARY
I have an auto-hidden panel on the left edge of my screen. When I move the
mouse to reveal the panel, the panel flickers for a moment.

STEPS TO REPRODUCE
1. Set up an auto-hidden panel on the left edge of the screen (only happens on
the left).
2. Move cursor to left edge of the screen so that it is over the task bar and
reveals the panel (not reproducible if it is over the application launcher or
configure panel icon)

OBSERVED RESULT
It looks like the cursor moves 1 pixel off the screen, then the panel shows,
the cursor is moved 1 pixel to be back on the screen and the panel flickers for
a moment.

EXPECTED RESULT
The panel shows without flickering or moving the cursor.
