Description: Setting the slide to a background color does not cover the whole slide during presentation mode. It seems like in normal mode there is something wrong as well but it's not as evident. It's easier to reproduce it using presentation mode. Steps to Reproduce: 1. Create a blank presentation. 2. Set the first slide background to a dark color, like black. 3. Start the full-screen slideshow. Actual Results: The one or more rightmost and bottom pixels are white. Expected Results: Full screen should be covered in the selected color. Reproducible: Always User Profile Reset: No Additional Info: Version: 25.8.2.2 (X86_64) / LibreOffice Community Build ID: 580(Build:2) CPU threads: 8; OS: Linux 6.12; UI render: default; VCL: gtk3 Locale: en-US (en_US.UTF-8); UI: en-US Debian package version: 4:25.8.2-3~bpo13+1 Calc: threaded

fpy, can you share your Help > About, please?
If, instead of setting the slide background to a color I draw a black-background rectangle that bleeds beyond slide dimensions, it is drawn correctly, no white lines appear.
