Describe the bug
The keyboard cursor bar is lagging behind where the characters are being inserted. It seems to get worse at the end of the lines.

To Reproduce
If the system option "Global scale" (for the display) is set to 125% it happens.

If set to 100% it works fine.

Expected behavior
Visual cursor is in sync with character insert position.
