Created attachment 189164 [details] Screen arrangement. SUMMARY When moving a (non-maximized) window to the screen edge, the window border (and shadow) are visible on the other screen as a thin line with a shadow right on the edge of a screen. STEPS TO REPRODUCE 1. Have two screens connected. 2. Move a window to the screen edge where the two screens meet. Using edge snap zone (under Window Management -> Window Behavior -> Movement) helps here a lot. 3. Observe the thin line and a shadow appear on the second screen. EXPECTED RESULT The 1 pixel (if my primary display is at 150% scaling) border shouldn't be visible on the second screen. SOFTWARE/OS VERSIONS Operating System: KDE Linux 2026-02-02 KDE Plasma Version: 6.6.80 KDE Frameworks Version: 6.23.0 Qt Version: 6.10.2 Kernel Version: 6.18.7-zen1-1-zen (64-bit) Graphics Platform: Wayland Processors: 4 × Intel® Pentium® CPU 4405U @ 2.10GHz Memory: 8 GiB of RAM (7.2 GiB usable) Graphics Processor: Intel® HD Graphics 510 - AND ALSO ON MY MAIN SYSTEM Operating System: EndeavourOS KDE Plasma Version: 6.5.5 KDE Frameworks Version: 6.22.0 Qt Version: 6.10.1 Kernel Version: 6.12.67-1-lts (64-bit) Graphics Platform: Wayland Processors: 32 × AMD Ryzen 9 7950X3D 16-Core Processor Memory: 32 GiB of RAM (31.0 GiB usable) Graphics Processor: AMD Radeon RX 7900 XTX ADDITIONAL NOTES: In attachments you can see the bug and my display arrangement (the bug appear both with 100% and 150% scaling) I'm unsure if this would be a "visual bug" or a feature/wishlist request. In any case, I think the border and shadow should be hidden from other screens until the window actually crosses onto other screens.
