Created attachment 182348 [details] showcase SUMMARY Stopwatch time is jittery STEPS TO REPRODUCE 1. Start the stopwatch OBSERVED RESULT Timer is jittery EXPECTED RESULT Not jittery SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.3.5 KDE Frameworks Version: 6.14.0 Qt Version: 6.9.1 Kernel Version: 6.15.1-arch1-2 (64-bit) Graphics Platform: Wayland
I couldn't reproduce this on the latest commit (9a4ab5b), and on the reported version commit (91416a3). Maybe it's something to do with which fonts are used for the stopwatch? There doesn't seem to be any code that enforces that all digits are the same width. Perhaps a simple fix would be to force a monospace font, instead of the default?
Okay, I can definitely reproduce this after I switch to a different UI font in settings.
