Weird jumps

[femans]

Describe the bug Often when the cursor is clearly somewhere in a document, and I press one of hte arrow keys or pageup/pagedown, the cursor jumps to the beginning of the document. If I do a combination like dd, it even removes the first line of the document in stead of the line of the cursor. Also, when I use end to jump to the end of the line, it does this, but then if I start typing or editing, it jumps back to where it came from.

To Reproduce I wish I knew. It just happens randomly and a lot.

Expected behavior Edit and move from where I see the cursor.

Environment (please complete the following information):

• Extension (VsCodeVim) version:
• VSCode version: 1.25.2
• OS: ubuntu

Additional context Unfortunately I had to disable the plugin because it becomes unworkable. Which may even mean I have to switch out vscode for something else.
