Keeps resetting view

[JMatthewsPH]

Mac Mini M2 Pro

Regularly resets, so you must select the source for each preview window again.

This is in Window and Fixed Window mode.

I'm seeing this as well, on an Macbook Pro (M4 Pro).

I tried saving the layout and selecting it as the "Apply layout on launch", but still had to select which window I wanted in each preview. I'm currently on v1.2.1-beta, but this was happening on "whatever version I was on before that" as well (I failed to note it when updating to see if an update fixed it).

I would like to add that it's been perfectly fine for the last hour with just two clients.

Same issue here — and it started not too long ago. It might be related to one of the recent Apple updates.

@Krakazybik @JMatthewsPH @rykugur Thank you all for the reports! I'll be looking into this as my top priority when I pick up work on this project, which should be soon.

Could you all please generate diagnostic reports as shown below, and email the diagnostic file to me at will@williampierce.io (privately)?

@williamcpierce The issue is no longer reproducible after reinstalling macOS and installing the latest update. Currently not experiencing any problems with the preview window resetting.

@williamcpierce Same for me, the problem seems to have stopped. I didn't reinstall anything, but I did install the most recent updates.

Issue is still there: reseting randomly.

I add some extra logging to get details about issue. In my case there 6 window opened and from time to time - randomly - it reseted. I created PR with workaround: resetting a stream after drop + extra logging. #409
