Created attachment 116105 [details]
Bunch of screenshots representing the issue.

SUMMARY
Some desktop effects fail to reproduce correctly, all related to the fade effect. They involve tray icons pop-ups, logout screen.

STEPS TO REPRODUCE
1. Update fedora to latest stable release (29)
2. Download and install kvantum, adapta look and feel
3. Select any look and feel except adapta, arc (and maybe others)

OBSERVED RESULT
The fade effects fail to work properly. In the fade out phase, the popup correctly fades but the background is a white, solid rectangle resembling the original popup shape. The logout prompt screen is not blurred-semitransparent anymore, but it seems the same white background is applied therefore the result is a quite gray uniform fill.

EXPECTED RESULT
The popups should fade out without white solid background, just like menus (and like they did before). The logout screen should appear semitransparent and let the desktop wallpaper be seen.

SOFTWARE VERSIONS
(available in About System)
KDE Plasma Version: 5.13.5
KDE Frameworks Version: 5.50.0
Qt Version: 5.11.1

ADDITIONAL INFORMATION
I'm not sure if kvantum was the real cause of this issue. It could be either related to the 29 update or to a recent dnf update which did not involve plasma packages directly though.
Also, as said above, the popup issue goes away when using adapta or arc look and feels/desktop themes. This is not true for the logout screen.
Feel free to contact me for more info. I think it should be easy for you to understand the underlying failure as it involves only some specific components of the plasma environment. Seems to be Breeze theme is not able to completely restore parameters ruined by Adapta AND/OR Kvantum.

If you disable the fade effect, you can't reproduce this bug, right?

Yes, regarding the fade out effect as you said. Not true for the logout screen issue.

Hmm, interesting...

Did you try to disable the Logout effect?

I did. All I got was the same gray screen you can see in the screenshots, nothing changed. Interestingly enough, the fact is checking or unchecking the option makes no difference at all AND the config dialog for that effect says "Plugin does not provide configuration file in the expected location". I really don't know if this is what it was like before, or it's one more funny thing to laugh at.
Comment 5 David 2018-11-05 19:01:10 UTC
Also, I don't know if this could make any sense to You Gurus, but it's also possible this whole situation started when I first connected my PC to a bluetooth speaker, which caused a really bad lag/glitch in the audio popup (audio device changed). This is the very first time I noticed the fade out bug.
But unfortunately I had Kvantum and Adapta installed only a few minutes before the connection so I really cannot establish who is responsible...
Comment 6 Vlad Zahorodnii 2018-11-05 19:06:50 UTC
Please post output of
qdbus org.kde.KWin /KWin supportInformation

Also, can you reproduce this bug if you disable background contrast and blur effect?

Ok, you are definitely a GENIUS. Disabling these effects corrected both the fade and the logout problems.

Blur   Contrast   Result
0        0         OK
0        1         Err, both
1        0         Err, both
1        1         Err, both

Is it still useful if I send you the out of qdbus org.kde.KWin /KWin supportInformation ?

Ok, Sorry Vlad, I didn't notice Contrast effect has 3 switch position (ON, OFF and half?) so the correct table is:
Blur   Contrast   Result
0        0         OK
0        1         Err, both
1        0         OK
1        1         Err, both

It definitely seems to be Contrast related

Thanks. :-)

Did you upgrade Mesa recently?

When a popup is faded out, does it flicker? What happens when you move a window over the white background?

I do thank you. I was going to reinstall kde if not Fedora.. I can't live without Plasma and I was going crazy trying to resolve this by myself since I don't know KDE enough XD

Yes, you're right again. The last update involved Mesa Packages. Exactly, these ones (dnf history):

If you downgrade mesa, can you reproduce this bug?

Yes, unfortunately. Downgrading Mesa from 18.2.3 to 18.2.1 doesn't resolve the issue. The behavior is the same, disabling the Contrast effect solves the problem.

I meant from version 18.2.3-1 to 18.2.2-1

Hi there, good evening Vlad.

You guys do everyday an incredible job. So proud to be a KDE user.
