Created attachment 151153 [details] Screenshot: (1) Screen 1 and (2) Screen 2 with the maximized window, whose shadow bleeds over. STEPS TO REPRODUCE 1. Two screens adjacent to each other 2. Open an application and maximize its window on one screen (in the screenshot it's a GTK app) OBSERVED RESULT If the application is focused, the shadow bleeds over to the other screen. EXPECTED RESULT If the application is focused, the shadow does not appear on the other screen as there's no real use to it but annoys a little bit. Shadows are as far as I understand meant to give some virtual depth when having two or more windows above each other. SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20220804 KDE Plasma Version: 5.25.3 KDE Frameworks Version: 5.96.0 Qt Version: 5.15.5 Kernel Version: 5.18.15-1-default (64-bit) Graphics Platform: Wayland Graphics Processor: AMD Radeon RX 580 Series
Can reproduce.
This issue seems to be a common complaint about the new outline in Plasma 5.27. It's not a new issue as shadows already exhibited it, but it seems to become more noticeable with the outlines. Maybe time to bump the priority, and maybe we can fix both at once, since they're both Breeze decoration elements.
I have tried to fix this issue, but I only managed to get the outline disappear when tiling for under one second: Window not tiled -> Outline shows Window snapped to screen edge -> Outline disappears for brief moment Window is done snapping to the screen edge -> Outline reappears I welcome someone else to try this, since I do not have time currently.

Can reproduce on KDE 5.27.10 Ubuntu SOFTWARE/OS VERSIONS Operating System: Ubuntu 22.04.3 LTS KDE Plasma Version: 5.27.10 KDE Frameworks Version: 5.104.0 Qt Version: 5.15.3 Kernel Version: 6.6.8-060608-generic (64-bit) Graphics Platform: X11 Graphics Processor: AMD Radeon R7 270 Series
Re-arrangement of monitors seems to fix the issue, re-arrangement meaning swapping Screen 1 and Screen 2, Screen 1 becomes the right monitor and screen 2 becomes the left. No bleeding happens when the screens are swapped so I'm not sure what's going on here
(In reply to Vince from comment #7) > No bleeding happens when the screens are swapped so I'm not sure what's going on here Nope. Gotta move the window to the other side now and check again, It is bleeding through.
Can anyone check if this is still an issue on Plasma 6?
(In reply to Vince from comment #9) > Can anyone check if this is still an issue on Plasma 6? In Plasma 6, I'm seeing the shadow still bleeding over for tiled windows, but no longer for maximized windows. The outline doesn't bleed over at all, as far as I can see.
The patch here https://invent.kde.org/plasma/breeze/-/commit/9b93fb968ed6a2817cee367aab5cfef7003b4073.patch works with KDE 5.27 and seems to partially fix the issue. I tested after logging out and logging back in. For maximisation, the window loses all outline even with the new setting Outline intensity set to Maximum. The only case not handled by the patch is snapping where perhaps the alternate screen should have the outline removed. This can be worked around by setting Outline intensity to Off.
