VLC for lectures, talks with slides etc.

So for many lecture recordings where the video is recorded in low fps (around 2 fps) and especially when you're watching them at speeds other than 1x, I've found that VLC usually doesn't update the video with the new video when it should (e.g. slide change). It can be fixed by disabling video track, then enabling it again.

However, to fix it properly, you can goto Preferences (Advanced/All) -> Video
Then uncheck the "Drop late frames" checkbox. I did not need to uncheck "Skip frames". And that fixed it, yay!
