Hey Everyone, we initially reported this via Twitter but were asked to post here, so here goes:
We’ve experienced some issues lately in our testing of Brave as related to video playback.
The first major issue is a lack of ability to load more than 2-3 tabs featuring video playback before the UI/UX is affected (slowdowns, soft crashes, etc.). It does not matter if the video is playing or not, once it is initialized we see this bug. This may be due to a leak, because of the second issue, as detailed below.
The second issue is that Brave is not releasing all the resources being initialized by the video player. This is what my task manager on Windows 10 looks like with Brave closed for over 12 hours:
When in this state, it also prevents Windows from sleeping or turning off the displays while idle. In order to clear this state, the tasks must be forcibly ended.
