Recording seems to be a bit faster than actual #4

I noticed that the resulting recording seems to be a bit faster than the actual speed of what's happening on the screen.

I was wondering the same. Could it be 30fps capture is not synced with 60fps source contents?

Also potentially related:

source timestamp
target timestamp (based on a QElapsedTimer)
buffer swapping

Not sure if this could help but MirVNCServer seems to have the correct speed. Also, setting the fps to 60 seems to fix it so likely an issue with 30fps. Nevermind, it seems to be too slow with 60 so I guess it's a general timing issue.
