Ubuntu 16.04.5 LTS, Atom 1.33.0 x64.
Could be theme related (using One Dark for UI and syntax) and could also not be a bug.
Anyway, I’ve noticed that, while editing, the background colour to the text seems to vary in blocks of 12 lines. Hard to explain, see images.
Anyone else experienced this? Is this expected behaviour? If so, it’s a bit annoying really.
