Created attachment 156318 [details] White line immediately above the panel SUMMARY The panel with the breeze dark application theme works fine when scaled at 1x or 2x or less than 1x, however, when scaled at 1.5x, a white line appears at the top of the panel (which can be very annoying if your panel is at the bottom of the screen). STEPS TO REPRODUCE 1. In the monitor configuration, set the scale of the monitor to 1.5 2. Create a panel at the bottom of the screen (so that the top half of the panel can be seen) OBSERVED RESULT a white line appears at the top of the panel EXPECTED RESULT There should not be a white line at the top of the panel, the whole panel should be black SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: gentoo linux 2.13 (available in About System) KDE Plasma Version: 5.27.0 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION
This problem only occurs with 1.5 scaling, 1.45x and 1.55x both appear without white lines
Created attachment 156326 [details] app launcher
Created attachment 156327 [details] notification window
It appears not only at the top of the panel, but also on the left side of the notification bar window and at the top of the app launcher
