Whenever my sim live-streams on the ultra-wide computer or the Streamer's First Computer from High School Years the screen appears transparent. I can see the back face of the monitor instead of the background screen on the computer. This has been happening since the pack released with or without mods. During other activities the screen appears normal, even when doing the SimsChat activity.

Generally bugs still open in the archive do not need to be re-reported unless you have new info.
