After upgrading to wayland 1.15 I'm experiencing display glitches with fullscreen windows (in my case Chrome) when there is another window behind (maximixed)

Additional info:
* package version(s)
extra/wayland 1.15.0-1
extra/wayland-protocols 1.14-1

Steps to reproduce:
- Open and window and maximize it (e.g. Nautilus)
- Open Chrome and put it in fullscreen mode (F11)
- Scroll up and down the page and look at the bottom

The issue won't occur if chrome is the only window around.

See attached screencast (look at the bottom of the window).
This task depends upon

I tested other applications and the issue seems to only apply to Chrome in full screen mode.

I also noticed that Chrome has become very jerky when rendering pages with images, semi transparent divs, WebGL contents etc since that upgrade.
Firefox still works fine and has smooth rendering

It seems an issue relevant to Chrome/Chromium only. I've opened a bug in Chromium bug tracker site:

Are you sure this is actually the wayland 1.15 upgrade? Did you test a downgrade?

Yes I did and it worked.
Also on GNOME on X session, the issue won't show up.

Do these xorg-server and xorg-server-xwayland packages help?
