Excuse me，I found another problem.After I set up mirroring on the external monitor, the message notification will not pop up.I guess it may be that the information notification pop-up window is on the virtual display.Is it a problem with my settings?
@waydabber @tangruilover Hi folks! I also encounter the same issue.

To be more specific, when I connect my MBP to external display, I always close its lid. And in this case, banner notifications can pop up as usual when BetterDummy is turned off and the MBP is only connected to the 2K external display. However, the notifications won't pop up when BetterDummy is turned on.

FYI, my MBP is the latest MacBook Pro 16'' with M1 Pro chip. And the screenshots below are the configuration of the dummy display and the real external display. The resolution of both the dummy display and the Dell 2K display is set to 1920 x 1080 for my personal convenience.

I wonder whether this issue is caused by some Apple's bug. @waydabber Do you mind taking a look? Thanks a lot ❤️.

The issue seems to be that you have to enable notifications in mirrored setups. Go to Notifications & Focus under System Preferences and change this setting at the bottom:

@waydabber That's so great! Sorry that I didn't find the option before as I'm new to the Mac. Thank you so much!

It's OK, I had to search for it either, the option is well hidden. :)

Found this hint by accident and missed some notifications in the meantime. ;-)

Maybe you can add this note to the Readme?

[waydabber]

Added. :)

Anyone know a good way to enable notifications for our virtual displays only, but not when sharing the display? The reason I have to use a virtual display is because my ultrawide screen's resolution is too high for high DPI scaling without using a virtual display. But I do want it to hide notifications when screen sharing

@vanakema maybe turn on Focus mode during screen sharing

That's a fair suggestion, but I don't think you can automate that unfortunately, which is kind of the whole point of the feature apple created
