SUMMARY
Kdeconnect consistently crashes when calling virtual display twice in a row.
Seems related to the interactions between the 'stop' method line 35 and the
'connect' signal line 152 of
'plugins/virtualmonitor/virtualmonitorplugin.cpp'.
STEPS TO REPRODUCE
1. Have 2 computers (A and B) paired with kdeconnect
2. Ask for remote display (kdeconnect drop down) on computer A
3. Cancel KRDC request on computer B
4. Ask again for remote display on computer A
OBSERVED RESULT
kdeconnect crashes on computer A
EXPECTED RESULT
Kdeconnect doesn't crash and tries to launch a new virtual monitor.
