"But my issue is really simple, I don't want to make a screen recording / notebook!

Please do it anyways! It is really difficult to know exactly what information we will need to solve the issue, and a video recording can save a lot of follow-up questions."

nearly stopped me reporting the bug. Is that what you want?

Bear in mind that I had to click on your link, login to Github and fill out your form, just to get to this comment. That was after something broke, which is frustrating, so I could easily have just ignored the thing.

Yes. We need your help in triaging bugs

I'm sorry if this caused you too much trouble.

Just rechecked this on my Windows Surface Laptop 3 (AMD chipset). Works fine on the latest released build (v0.19.27).

The original problem occured on my Macbook Air M1 (ARM chipset). Same Pluto version. Still doesn't work.
