Weird bug on top pannel

[deoktr]

Describe the bug
The blur effect stop before the middle of the screen leaving a weird block with a clear line almost like the effect was compressed to around 40% of the screen width.

Expected behavior
Normal blur without any artifacts.

Configuration

• GNOME Shell version 3.36.6
• Distribution Manjaro
• Xorg 11 session
• Matcha Dark Azul for the gnome shell theme, and it's the theme who put the transparent top bar

Screenshots

Additional context

• No other extensions changing the shell design
• Using dual monitors (the shell is on the main one)

GPU and CPU dosen't matter because I could reproduce on 2 instalation of Manjaro on different computer.

Do you have a custom shell theme? I don't think the search box is natively that transparent.

[deoktr]

You'r right the problem seams to be linked to my shell theme (Matcha Dark Azul) wich change the transparent top bar and search box.

I could reproduce with this options:

• Apply Effect to: Activities + Panel
• Blur Intensity: 10.0
• Activities Background Brightness: 1.00
• Panel Background Brightness: 1.00

With the default theme I can still see and artifact (the white line under the top bar) wich is like the previous screen not spanning the full width, and again no other extensions changing the theme, I can see it when I have my custom theme and if I change it after I already got the artifact.

The bar is also visible outside app view

The line is only visible if the 'Apply Effect to' option is set to 'Activities + Panel'

I think that the dual monitor setup causes this bug. @2o4 is your secondary screen to the left of the one you took a screenshot of?

[deoktr]

Yes my second monitor is on the left.
I don't know if it's of any use but it's portrait so: 1080x1920
