Works but sometimes it gets stuck and takes longer than actually watching the ad. fix it and I will give you 5 stars

Hey, I am not sure where I should post this but I am having issues with my Opera GX. It started about 2 days ago, every time I go to a streaming site like Twitch.tv, the video stream turns like this...

Does anyone know how to solve this? The stream can play normally in full-screen mode as well as picture in picture but it goes all blurry in normal view and the controls are unresponsive...
Please help~ anyone~
