Git commit 6aa40563040b0ec4d1fde8a701b5fa4e0951f16d by Tomaz Canabrava, on behalf of Luis Javier Merino Morán. Committed on 07/06/2021 at 18:03. Pushed by tcanabrava into branch 'master'. Only generate autoscroll events while selecting As gumix explains in the bug below, "Konsole keeps sending mouse-drag reports in ESC[?1003h mode after releasing button outside window [...] The only way to stop it is to get mouse back over Konsole window." These mouse-drag reports are actually generated by AutoScrollHandler, to support the use case of extending the selection by dragging the mouse outside the display area. So, only generate those reports while selecting. Can be tested by playing around in vttest: - 11. Test non-VT100 (e.g., VT220, XTERM) terminals - 8. Test XTERM special features - 5. Mouse features - 7.
