Non-blurred widget after first login

SUMMARY
Hi, I hope this is the right category for the bug. 
Widgets under 5.24 are only blurred, when I log in a second time. From cold boot, they are always opaque.


STEPS TO REPRODUCE
1. Place a widget on the desktop with a theme that supports blur (Breeze) 
2. Shut down the PC completely, then boot it, log in
3. Widget is not blurred (the top bar in edit mode, where you can set a global design or configure display settings isnt either, dont know if related)

OBSERVED RESULT
Widgets are not blurred after cold start, only after relogin

EXPECTED RESULT
Widgets should be blurred all the time when a supported theme is used

Does it reproduce on Wayland too? I cannot reproduce on Wayland.

Does it affect only widgets on the desktop, or also the popups for widgets on the panel?

Are you using any non-default themes?

Hi Nate, thanks for getting back.

"Does it affect only widgets on the desktop, or also the popups for widgets"

Im not sure what you mean with popups for widgets, if you mean what happens, when I hover my mouse over, say, my volume next to the clock, then yes, these things are not blurred. 

"Does it reproduce on Wayland too? I cannot reproduce on Wayland."
Correct, on Wayland the widgets do blur correctly, just not under X11.
However, what I described above about hovering my mouse over items in the taskbar is still correct. These things do not blur.

"Are you using any non-default themes?"

No. I tested with Breeze light and dark, as well as with the theme that came with my distro (Tumbleweed). 


Additional thing I discovered:
At least when using Wayland (didnt test under X), when there is an icon under a widget, it does not blur the icon, but only the wallpaper. I dont know if thats intentional, but I expected it to work differently, as in that the blur is applied to the widget, no matter whats below it.
Also, as stated above, the "edit bar" at the top when in edit mode is not blurred (in both X and Wayland), but I remember it was in past releases.

Thanks! Sounds like there is something wrong with the blur effect as applied to everything; moving to KWin which provides the blur effect.

Background behind widgets is blurred by plasma.
Comment 5 Marco Martin 2022-02-14 08:13:53 UTC
can you also put a screenshot of the blurred ones?

IF blur actually works for once, so after a second login, only the wallpaper is blurred, but not icons below (if thats what you meant with "background", I assume by saying background you mean everything below a widget)

Sure. Both versions in comparison: https://imgur.com/a/INzbOdK

Re-posting the screenshot here, so we don't depend on external resource (imgur seems to be "down" under my VPN, for example).
