I am using an Acer Nitro 5 AN515-54-52H2
Spec - i5 9300H, GTX 1050 (3GB)
Windows Version 1909
I am facing this issue, wherein when I plug my Charger, certain applications start playing videos in a manner that seems horrible. The video gets back to normal when I unplug the cord.
This issue has persisted across 2 Intel Driver versions, 4 or 5 NVidia Driver Versions.
Applications that exhibit this issue are mostly Microsoft originated - Movies & TV App, Skype and Windows Media Player are the main culprits.
