#5894 reports that when running a Textual app under Windows Terminal with
mouse=False
, the console gets polluted with garbage characters when the mouse is moved during and after the app's execution.The issue is caused by an extraneous line in Textual's Windows driver. That line enables mouse support regardless of the
mouse
flag. However, mouse inputs are not handled whenmouse=False
; nor does the clean-up routine disable the mouse support whenmouse=False
. As a result, control sequences that encode mouse events are treated as regular input, and the screen gets polluted.This PR fixes the issue by removing that extraneous line.
