Thank you for the report.
However, under my environment, it works correctly.
Please inform me any other conditions that may relate to the behavior.
Uploading a recorded movie also helps me.

I put a screen recording in youtube, according the recording, it's not the cursor problem, it's the space is missing, please note the column number at left bottom, when I input Space, it up to 12 and back to 1 when I move the mouse.

Oh, I got it! Thank you.
This is a bug that relates to "Trim trailing whitespace on save" option.
I'll fix it in the next version that may be released in this weekend.
Please be patient a while.
