Here's something I've noticed recently while using vMix as an AV presentation tool for an event.

Prior to the start of a recent event, I had a PowerPoint presentation of sponsors running in a loop. When the event started, I switched to other images, camera, and PowerPoint inputs with no issues. However, when I began to playback of a few videos, I kept getting flashes of the pre-show looping PowerPoint screens injecting themselves over my video. Once I realized what was going on, I scrolled over to that PowerPoint input module and pause it. Once I did that, i didn't have an issue anymore.

Not sure if this is a vMix issue or my laptop, an HP 17" Envy with an Intel graphics chip, which is not known to be the best graphic card out there.

Any thoughts?
