Text selection highlight doesn't update when scrolling down

When scrolling down while selecting text through several screen-fulls, the highlighted region doesn't update.

I can reproduce this on latest master, under Wayland (sway). I'm happy to provide any other information that may be useful.

It's just temporary, while scrolling, as soon as you stop, it will re-adjust. Obv would be nicer if it adjusted on the fly.

Thanks for the quick fix, it's nicer now 😄

I think there's just one visual glitch left: if the selection starts somewhere in the middle of a line, the part left of the start is never shown as selected after scrolling past its initial position.

The unselected top-left-corner updates as I scroll up after finishing my selection.

This seems to persist even after scrolling has completed.

That should also be fixed in master.
