Option to disable animated UI transitions - Feedback / Suggestion - PIA Support Portal
Similarly, when dismissing the notification are icon UI, it takes most of a second to "fade away". You have to wait before you can click whatever other thing was behind the PIA window. Again, it just makes the app feel slow.
The Disable Accelerated Graphics option has no relevance to this suggestion. The animations occur whether that option is on or off.
Thanks for your consideration!
