Hi,
I have the same issues here. I am using an Intel NUC with integrated infrared MCE receiver. Since update to 8.2 the remote isn't usable anymore because all keypresses are doubled.
So I plugged in my old Hama Remote (Hama MCE Remote Control PC-Fernbedienung: Amazon.de: Computer & Zubehör) with external IR receiver. This remote works better but far away from perfect. When I press a button two or three times fast, it will be interpreted as a long press which will cause a great leap forward of the cursor. And often single keypresses are totally ignored. So I have to press the buttons carefully. In short: frustrating!
I'm a little bit upset because none of my remotes work properly anymore.

Edit: RFTM.
After disabeling LIRC in the Services-Menu everything seems to work again now. Maybe LIRC should be disabled by default.
