Hello, it's happening a strange thing. Sometimes I use a window of firefox on the first monitor and another on the second monitor, that's fine here. But if I play like a video on the second window and I browse internet on the first one the video on the second monitor will block, but the audio works.. Most of the time it happens when I browse facebook but it happend even while typing this help question so... To fix this I just need to move the cursor on the video... I'll link a video to let you see: https://streamable.com/whil7y
