In VSCode I use F8 regularly to jump to the next error and by default a box will appear below the line with the error/warning (outlined red for errors and yellow for warnings). It is not a popup, it pushes the lines of code below down and is inserted inbetween. I'm not sure if this is a RA feature or VScode. Does anybody know the name of this feature and/or how to disable it?
it's a vscode feature, the box you mentioned is usually referred as the peek view or inline view (I don't know the official name).
unfortunately, I don't think you can turn it off for the F8 command. see this similar question:
