Multi-Monitor - Dimming for selection based screen capture takes a long time

[Mark M]

I'm probably an edge case, but I'm sure this affects other people with multiple monitors.

1. Start screen capture
1b. (Errors pop up)
2. Program appears to be frozen
3. Some time later the screen capture is ready

1b.

Errors displayed on startup:
Error while adding the file monitor.
Unsupported operation
(Displays twice)

Console Errors During Startup:

        (Maybe you should just omit the defined()?)
