@a6ff0b2b Maybe it's related to the mouse polling rate and the Microsoft mouse connected over USB has a higher polling rate than the Logitech or when connected via Bluetooth? The higher the polling rate the fewer open windows it takes to reproduce the issue. 

 @134318c2 Yeah. I've actually given up on posting something from mobile before and made a note to post it once I was back on my laptop just because the alt text interface in most apps is so terrible.

Firefish has one of the better interfaces at least. You can see the entire image and get a multi-line text box as well as auto-transcription.
