look at the bottom of the dock, when it is transparent, there's a bar with blur below it and when it has a background with blur it looks conjoined with the bar.

if you look at the bottom bar on libreoffice around the part where it says "default page style" you can see it clearly.
Comment 13 phoenix. 2021-03-07 09:47:39 UTC
also another thing, the dock is hidden in this picture as well as it is transparent, this is the bar im talking about which shows up when youve left the dock hidden for some time (can fix by minimizing all windows and reaching the desktop with one windowed app open) and when you use the dock.

1. Please provide a full size video to understand what you are describing, you can use Google Drive and DropBox to upload it and specify exactly the second you observe the problem. The video is imgur is too low res and I can not observe what you are describing.
2. If you [disable] in Appearance advanced settings -> Hide background when not needed, is it fixed for you?

https://invent.kde.org/plasma/latte-dock this is the correct one, the previous one I think is deprecated for more than five months for all kde projects

you thing i wanted to ask though, can this be caused by kvantum?
i think it might be registering the area where you hover to bring up the dock as a blur-able area of an application which in this case is latte

Oh... you could test this by changing to Breeze Application Style in plasma systemsettings. I can understand now what is the issue but the thing is that I can not reproduce it in my system...

If you increase the screen margin a lot, you get again blurred area for ALL the screen margin?

yes, sometimes. also, an interesting development, the blurred bar thing goes away on applications when using the breeze system theme but if "hide background when not needed" is enabled it comes back when the dock goes transparent/hides the background on the desktop.

Ok that would make it a kvantum related issue...

Try to enable Breeze application style and Breeze Plasma theme, relogin your system and test afterwards if it is reproducable.

In my system I can not reproduce any such issue. I suppose I will leave it open until more users are hit by it and a concrete way is found to reproduce it.
Comment 36 Michail Vourlakos 2021-09-05 06:14:42 UTC
propably kvantum or something else paints latte windows even if it should not, so this is not latte issue
