I have some folders in which I just get a notification that a task needs to be done. Afterwards I directly delete that email. Doing the same with the new GMAIL resource, leads to unexpected results/issues. 

I select the email to be deleted and press the Del-key. Nothing happens and the email is still there. Restarting KMail resolves this issue as that the email is now gone. However this results in a different issue as that the gmail resource detects an inconsistency between local and remote as that it never succeeded to delete the email remotely. The resource is now performing a full resync which has as a consequence that the deleted email appears again. 

The output log from akonadictl is:
