***


STEPS TO REPRODUCE
1. install easy-stroke
2. setup a mouse-gesture-action and make sure you choosed to display the mouse-movement as osd (in easystroke settings)
3. do a mouse-gesture

OBSERVED RESULT
The mouse-gesture has an black background now (wasn't in previous version of plasmashell) and stay for > 1 Minute
In the Attachement you found a mouse-gesture "P" - you can see the black filled background.

EXPECTED RESULT
The mouse-gesture (osd) should be transparent and not with filled black background.
The osd should disappear after some seconds (3-5 Seconds)

This was a mouse-gesture which stay's for round about 1 minute at the screen

Comment 3 Nate Graham 2021-11-23 18:48:45 UTC

This doesn't look like any notification that comes from any KDE code. It seems like an app bug, unfortunately.

Comment 4 Samuel Suther 2021-11-23 18:50:30 UTC

It works like a charm before last plasma upgrade.
The point isn't that there is an error with the app itself, it is, that the osd has this strange background-color now (was transparent before) and stay for a long time at the screen... even if it should disappear after 3 seconds.

Comment 5 Nate Graham 2021-11-24 19:13:10 UTC

Maybe it's a KWin regression then.

Black squares

Also having the problem.

When using regular gestures, the black squares disappear immediately, but when using a gesture to change the virtual desktop, they stay and some parts start flashing.

And not sure if this is related, but I now occasionally get a crash (return to login screen) when I start a gesture, roughly around 1 crash at every 200 gestures or so.

Comment 7 Samuel Suther 2021-12-20 10:42:22 UTC

Got some new insights at it.

If I switch in EasyStroke - Settings for the Method to show Gestures from "Default" to "XShape", the error disappear. 
Unfortunately the setting switch back to "Default" after reboot.

Comment 8 Nate Graham 2022-09-08 16:36:23 UTC

Are you able to reproduce this issue in Plasma 5.25 or later and the latest version of EasyStroke?

Comment 9 ioutro 2022-09-12 18:40:29 UTC

Cannot reproduce in Plasma 5.25, thanks!
