@joshsweaney Can you talk about your monitor/hardware setup a little bit? I tested this briefly on macOS, and the preferences window opens appropriately on top of the main window.

This longstanding Electron seems related: electron/electron#1836

Looks like that electron issue could be the cause of it.

I have two monitors plugged into my machine, one of VGA and one on DVI.
1920x1200 is primary monitor,
1680x1050 is secondary monitor.
Both connected to integrated graphics (no discrete GPU).
Windows 10 (10.0.16299)

If I place the Signal window on the secondary monitor and select any option which opens a secondary window (e.g. preferences) it opens on the primary monitor.

Reproducing the issue with Kubuntu 19.04.

2x 1920x1080 displays. The "preferences" UI always shows up on the display marked as "primary" by Kubuntu's display manager. The preferences UI is also missing window decorations and cannot be moved or re-positioned.
