SUMMARY While fractional scaling is enabled (in my case I have 2256x1504 and 3840x2160 monitors, both scaled to 150%), sometimes changing the monitor layout can cause some apps like Discord to scale back down to 100%. This is potentially (though I'm not completely sure) caused by disconnecting the primary monitor while the window is on the secondary monitor. STEPS TO REPRODUCE 1. Open Discord on the secondary monitor with fractional scaling enabled 2. Disconnect the primary monitor, making the secondary monitor now the primary monitor 3. Observe Discord, try to resize it, etc OBSERVED RESULT The app is now rendering at 100% scaling EXPECTED RESULT The app continues to render at 150% scaling Operating System: Kubuntu 24.10 KDE Plasma Version: 6.1.5 KDE Frameworks Version: 6.6.0 Qt Version: 6.6.2 Kernel Version: 6.11.0-13-generic (64-bit) Graphics Platform: Wayland Processors: 16 × 12th Gen Intel® Core™ i5-1240P Memory: 31.1 GiB of RAM Graphics Processor: Mesa Intel® Graphics Manufacturer: Framework Product Name: Laptop (12th Gen Intel Core)
Thank you for the bug report! However Plasma 6.1.5 is no longer eligible for support or maintenance from KDE; supported versions are 5.27. (LTS), and 6.2 (non-LTS) or newer. Please upgrade to a supported version as soon as your distribution makes it available to you. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one. If you need support for Plasma 6.1.5, please contact your distribution, who bears the responsibility of providing support for older releases that are no longer supported by KDE. If you can reproduce the issue after upgrading to a supported version, feel free to re-open this bug report.
