Orion sometimes starts stuttering / garbles audio during playback (e.g. from Youtube). It's random but usually happens the longer I am playing back videos (i.e. rarely/never at the beginning of the first video I play) and have lots of other windows open.
Attached was a video but just realized that it didn't capture the audio. Will try capturing the issue with my phone videoing the screen next time this happens.
Also I have process samples of both the top-level Orion process and the Web Content process that I believe is associated with this playback (it has the highest CPU% during playback). CPU usage was also a bit high for playing this video back -- 120-150% of CPU which seems high for a 720p video on a not terribly old processor (10th generation Intel).
Note that in this example this was only the second video I played in that window. I believe I played just one 15 minute prior to this one. Sometimes in the past I've seen this issue arise after a somewhat longer viewing session but this happened pretty quickly. Also I didn't have very many windows/tabs open this time (6 windows and 7 tabs including the Youtube and the other windows were mostly static text).
I expect the video to playback smoothly with the full audio fidelity of the tracks embedded in the video without stuttering without stuttering. It should do that for the full duration of the video and continue playing back smoothly video after video (e.g. if I let Youtube autoplay the next video and so forth).
