Cursor not refreshing.

[chedieck]

Sometimes, after making a jump, the cursor is theoretically moved but it does not refreshes: it still shows the old position.
Actions such as pressing <Esc>, moving to another buffer and back, pressing :, doing any other cursor movement: they will refresh the cursor or assume that its position was the right one, which is not the one being shown.

I recorded three viedeos to show better the bug:

First, I type sSos and the cursor is moved, but it does not show that it was moved. Then I press l and it goes a character to the right, showing where it really was.

Here I type sSos and the cursor is moved, but it does not show that it was moved. Then I press : <Esc> and it shows in the right place.

doing sSs works normally.
