I have been using JuliaPro version 1.5.1-4 for a couple weeks now and I encounter this frustrating bug where after working a while on some .jl file, when I try to preview the values of a vector/array/…, the code disappears (the screen turns black partially or fully) and I have to close and reopen that same .jl file again. Attached is a screenshot of one incidence.

Sounds more like a bug in the editor, but that’s just a guess. Maybe just try to update julia, atom and juno and see if it goes away.
