This worked fine with PS 2.9, however, in 3.0 Alpha11 (as compiled and shared by Nomad on Discord), the scaling does not work, and I'm left with hard-to-read text and very small buttons. This gets a little better when I increase the application font size in settings, but this is very limited help because text begins to be cut off when I increase the font size by more than a few points.\n\nPrusaslicer version:\nPrusaSlicer-3.0.0-alpha11, installed from the file PrusaSlicer-3.0.0-alpha11-local.flatpak shared by Nomad on Discord.\n\nHere is a screenshot with the best I could do with increased font size:\n\u003cimg width=\"2880\" height=\"1800\" alt=\"Image\" src=\"https://github.com/user-attachments/assets/a21e1f7b-bd02-485a-a8ad-d2f8a7777086\" />\n\nHere are my full system details:\nOperating System: TUXEDO OS \nKDE Plasma Version: 6.6.5\nKDE Frameworks Version: 6.24.0\nQt Version: 6.10.2\nKernel Version: 7.0.0-110030-tuxedo (64-bit)\nGraphics Platform: Wayland\nProcessors: 16 × AMD Ryzen 7 8845HS w/ Radeon 780M Graphics\nMemory: 64 GiB of RAM (60,6 GiB usable)\nGraphics Processor 1: AMD Radeon 780M Graphics\nGraphics Processor 2: AMD Radeon 780M Graphics\nManufacturer: TUXEDO\nProduct Name: TUXEDO InfinityBook Pro AMD Gen9\n\n### Zipped project file & How to reproduce\n\n1) Install PrusaSlicer-3.0.0-alpha11-local.flatpak on Linux\n2) Set fractional scaling (I use 175%)\n3) Open PrusaSlicer-3.0.0-alpha11\n\nResult: All text and elements are very small and hard to read because scaling is ignored.\n\n### Version of PrusaSlicer\n\n3.0.0-alpha11, as compiled by Nomad (PrusaSlicer-3.0.0-alpha11-local.flatpak)\n\n### Operating system\n\nLinux\n\n### Operating system version\n\nTuxedo OS (Based on Ubuntu 24.04, running KDE Plasma under Wayland)\n\n### Printer model\n\nCore One+","author":{"url":"https://github.com/philip-soerensen","@type":"Person","name":"philip-soerensen"},"datePublished":"2026-09-02T15:44:08Z","url":"https://github.com/prusa3d/PrusaSlicer/issues/15675"}
