A strange poltergeist is going on with the console. Sometimes, when starting programs, a series of spaces falls out into the console exactly in the height of the console, it resembles clear in linux and interferes with life. At first, this behavior was in git bash when starting node, it ruined the output to the console =( It seems that I won by "correcting" aliases.sh, literally commenting out the contents. But it only helped with node.js, npm was not in the list, and it sometimes makes an output spaces.And how ba dumped everything on git bash, but installed atom with the "platformio ide" plugin, and the same problem pops up there when opening the console.
