Well, after a bit of poking around it seems that the problem isn't related to
the pointer being hidden(I managed to reproduce it while the pointer is still
visible, but the video lags). However I managed to record the framerate, and
there is a noticeable drop - from 60fps when it plays smoothly to 30fps when it
lags.(Framerate recording isn't the most reliable, but still it shouldn't vary
so much)

1) Yes, this is through Xwayland

2) No, there are no processes that use more than 1% CPU(and they have the same
cpu % as before playing the video), it's just chrome that uses CPU.

Is this going through Xwayland?

One thing that comes to mind from hiding a cursor is that some other surface
could be promoted to the cursor plane given size and format restrictions. The
cursor plane path is pretty copy-happy.

Do you see any process hogging the CPU more than usual when the lagging
happens?

Bug ID: 101162
   Summary: Chromium videos are lagging once the cursor is hidden
   Product: Wayland
   Version: unspecified
  Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
  Severity: normal
  Priority: medium
 Component: weston
  Assignee: wayland-bugs@lists.freedesktop.org
  Reporter: iliy...@hotmail.com

To reproduce the issue(at least on my machine this is the behavior, I'm using
weston 2.0.0):
Open chromium/chrome, load a youtube video, leave the pointer above it, after a
few seconds it will "hide". At this moment the FPS of the video drops
considerably(or probably this is the compositor's FPS) and the video lags. When
I move the cursor again so it becomes visible the problem goes away until it
gets hidden again. This doesn't happen with fullscreen video, maybe the black
surfaces that weston uses or something similar is the reason behind this, as on
my WM it happens with fullscreen windows and I don't use black surfaces.
