Description: LibreOffice's Tabbed UI has the following graphical bugs when using the KDE Plasma desktop environment: 1. Tabs are vertically misaligned by -2 pixels and droop down below the tab dock. 2. Tab shapes are inconsistent: sometimes they are completely rectangular, and other times they are rounded without respect to the shape of adjacent tabs, leading to jarring visual results, 3. The tabs themselves are an unappealing dark grey, whereas on other desktop environments the tabs take the same colour as the dock they are drawn against. I have reproduced this on multiple Linux distributions, and the results are consistent: LibreOffice always has these issues on KDE Plasma, and never on GNOME or Cinnamon. Steps to Reproduce: 1. Run any Linux distribution with KDE Plasma desktop environment 2. Select the Tabbed UI for LibreOffice 3. Observe Actual Results: The aforementioned graphical bugs as per the Description field. Expected Results: Tabs should be aligned 2 pixels higher vertically. Tab shape should be consistent. And preferably, tabs should be a lighter grey, like the dock they are drawn against. Reproducible: Always User Profile Reset: Yes Additional Info: Version: 24.8.7.2 (X86_64) / LibreOffice Community Build ID: 480(Build:2) CPU threads: 4; OS: Linux 6.12; UI render: default; VCL: kf6 (cairo+xcb) Locale: en-GB (en_GB.UTF-8); UI: en-US 24.8.7-3 Calc: threaded
