Rules are not applied until the email is open

Hi, I’d like to report that email rules don’t seem to be applied when the email has been received as stated in the application settings, but only when the email has been open and seen.

In my case, I have a rule currently set to delete emails automatically if a specific word is inside the email body. The rule works well but it doesn’t really gets applied automatically but I need to select the email and wait for 0.5 seconds before the email is automatically deleted, as you can see from the screenshot below, there’s a spinning wheel running as if the email content is being loaded.

Of course, if I have to manually select each email I need this rule to be applied for, it would be faster to do things manually.

I am using Version 1.9.2

Is anyone looking into this?
