[Bug 1493106] [NEW] Dash randomly becomes transparent to mouse events

 

Public bug reported:

Don't tell me "can't reproduce". Almost surely you can't. This has just
happened to me randomly, it will probably disappear at the next reboot
and it will probably be ages until the next time it randomly happens
again. However this is HUGE.

Dash has suddenly become transparent to mouse interaction. For example
- I click on the Dash icon on Launcher
- (optuonal) I type the name of some application
- I click on the icon of some application that I want to launch

Instead, I am clicking on whatever is behind it.

This is a CRITICAL SECURITY ISSUE, as you may accidentally click on a
button to confirm some destructive action (or to send an email before
you finish writing it), if it happens to be behind the icon you are
trying to click.

You can LITERALLY (and I'm not abusing the word "literally") format your
hard drive because of this bug.

Besides, obviously, rendering Dash unusable and making you unable to
launch any application.

When the issue appears, it won't go away. I tried ctrl+super+D twice,
clicking on random other launcher icons, and the like.

The only workaround I can think of is reboot.
