I ran into this on a dual-monitor setup, had FFDec open on a 4K monitor, then switched to a regular 1080p monitor and the UI was massive, couldn't click anything. jpexs saves the detected DPI scale to config on first launch. Next time it sees a saved value and skips detection entirely, so it stays at 4K scale even on a lower-DPI screen.
Fix: stop saving the auto-detected scale to config. It now re-detects from the current screen on every launch. Manually configured gui.scale in settings is still respected.
Note: if you've hit this bug before, you may have a stale gui.scale entry in your project.properties config file. Deleting that line will let the fix take effect.
