App misbehaving when creating the preferences pane

[HalfVoxel]

Creating a new issue

The buildPrefsWidget just spawns a separate process with the actual preferences. This is bad because there will be a leftover non-responding application. If you focus this leftover application using alt-tab it shows a "This application is not responding" dialog which just looks bad.

Yep, this is not really elegant. But with a GTK4 rework, this issue will become irrelevant. Therefore, the current version will not be fixed.
