Description Nicholas Serrano 2021-01-07 18:59:16 UTC 
SUMMARY
Since commit https://invent.kde.org/plasma/latte-dock/-/commit/ba94315ecbc5b5b7367109573ca6687506897963 anytime the dock hides, it is impossible to make the dock appear again with a mouse. This affects the “Dodge All Windows”, “Dodge Active”, and “Autohide” visibility modes.
Latest commit I’ve tested: https://invent.kde.org/plasma/latte-dock/-/commit/f8cce7acfad89df205cf2a884f9f02bebba10468

STEPS TO REPRODUCE
1. Change dock to one of the above mentioned affected Visibility modes.
2. Let dock hide, either by packing window above dock or waiting for autohide timeout.
3. Move mouse over dock area

OBSERVED RESULT
Nothing happens

EXPECTED RESULT
Dock should appear

(In reply to Michail Vourlakos from comment #1)
> In which screen edge?

In my case the bottom edge.
Comment 3 Michail Vourlakos 2021-01-07 20:09:39 UTC 
I can't reproduce, please provide your layout file.

Current Layout file

This is my current Latte layout.
Comment 5 Nicholas Serrano 2021-01-07 20:28:24 UTC 
After some more research, I found that the behavior works as expected when "Activate Kwin edge after hiding" is enabled. I currently have it disabled while latte has it enabled by default in the other layouts.

Thank you, I will check it out, your findings are pointing in a very specific direction in order to debug.

fix input mask area length calculations

--effects area is not relevant when the dock is
hidden, in such case using localGeometry is a much
better approach and more accurate.

Just tried out the newest commit. Looks like it’s resolved while "Activate Kwin edge after hiding" is disabled. Thanks!
