Window decoration blinks when i'm hovering over wingpanel

Good catch! I think this issue and https://github.com/elementary/wingpanel/issues/220 are related to whether the Wingpanel (this includes the indicator popovers) has focus. The window decoration probably blinks because it's switching between having focus and not having focus.

There was one recent focus related change: https://github.com/elementary/wingpanel/pull/206.

You also made me notice: https://github.com/elementary/wingpanel-indicator-notifications/issues/69 (Never noticed it because I have the power indicator (battery) in between)

[peteruithoven]

I actually think it's a race condition between the wingpanel restoring focus to a window and the wingpanel regaining focus. This race conditon might have worsened since this improvement: https://github.com/elementary/wingpanel/pull/155

I can confirm exactly the same behavior on this machine, with additional problem of all new opened app windows going background instead of foreground:

...and the same blinking on this machine, but here all new windows open normally in foreground:

[peteruithoven]

I think I've solved it with #222 please feel free to give it a go, see if that solves it.

(Btw, what kind of logs are those? Could use some context there)

[DanyGee]

Those logs are from INXI app. I find it the most useful till date hardware listing app for bug reports.

I think I've solved it with #222 please feel free to give it a go, see if that solves it.

Is there an easy way to try it without compiling too much? :sweat_smile:

[peteruithoven]

Seeing there is no such thing as compiling just a little, I'm afraid not ;)

[DanyGee]

I'll wait for an official update then. THX!
