Crashes / Tab Issues When Idling and Resized

I am not sure how to completely reproduce this, but have experienced a crash when I use regular RDP to an instance (ie - juimp server) and run mRemoteNG in that RDP session. When the RDP resizes or if I disconnect, I notice that in some special instances mRemoteNG tabs will become messed up and disassociate with the RDP session. They cannot be closed or removed unless you exit the app. I don't know how toi reproduce this 100%, but noted that it happens when mRemoteNG remains connected in an RDP session and is resized, or some time passes

I have two stack traces that are possibly related:

Expected Behavior

• Tabs should not become unassociated from their RDP instances or lose control from the UI

Current Behavior

Tabs stop working if the application is idle in an RDP session and that parent RDP window is resized or reconnected. It is not exactly reproducible every time, but happens a lot
