Description Connor Farrell 2023-01-27 13:03:56 UTC
SUMMARY
The log out dialog has an excessively darkened bar on multi-screen setups

STEPS TO REPRODUCE
1. Have more than one screen active
2. Start the log out dialog

OBSERVED RESULT
An almost completely black bar appears on the edge of all screens.
Which edge is affected changes depending on the relative placement of the screens.

EXPECTED RESULT
All areas of the screen are equally darkened.
The visuals are independent of the amount and placement of the screens attached.

Looks fine to me

Cannot reproduce; see attached screenshot.

Are you sure this black bar isn't simply the blurred representation of something on one of your open windows or your desktop wallpaper?

.
Comment 7 Connor Farrell 2023-04-19 17:08:13 UTC
I just retested and this also occurs with a homogeneous white wallpaper, all windows closed and a single white panel.
While testing I did however notice a few more things:
- It only occurs on wayland sessions
- It only occurs with the blur effect enabled
- It is barely noticeable unless the background contrast effect is also enabled
Comment 8 Nate Graham 2023-04-20 15:13:02 UTC
Weird, I'm on Wayland with the Blur and Background Contrast effects enabled too. So if you turn those effects off, the issue goes away? That could point to it actually being a KWin issue or a GPU driver issue.
