What happened?

See gif below. The screen "splits" within the editor causing a visual error and strange scrolling behaviour and a horizontal scrollbar in the wrong place.

Which OS does this happen on?

🐧 Debian based (Linux Mint, Ubuntu, etc.)

OS details

Linux Mint 20.3

Which CPU architecture are you running this on?

64-bit(x86_64)

What steps are needed to reproduce this?

I haven't been able to replicate this as such. The file itself is an untitled file with content. I had a ton of tabs open and was clicking rapidly to close the ones I didn't want and this error showing on this tab.

(I had to lie about replicating in safe mode as I can't reliably replicate this yet I've seen it a few times).

Additional Information:

Dev version commit f4dfa048c

This is apparently an old Atom bug that is yet to be resolved and is difficult to replicate reliably. Logging it so we can keep track and refer any duplicates.

Discord conversation.

Console logs checked but nothing of relevance.
