Thanks for the report! This appears to be happening because Bubble Tea keeps the cursor in the lower left position while the various input types in Bubbles render a virtual (simulated) cursor. To solve for this we'll need some changes to the renderer, a low level cursor API, and some updates in Bubbles.

Just a note that we're actively working on this as part of a larger renderer upgrade underway internally. No ETA but so far things are looking good.
