Public bug reported:
If I'm using Chrome under Wayland, and I pick a tab, and drag it out of
the current window, it correctly creates a new window. But this new
window has performance issues, and often freezes for a few seconds while
using it. The original window seems to be affected as well, but to a
lesser degree, in my experiments. Other windows seem to be unaffected.
I also checked it was not a one-session problem, so I logged-out and
back in, tried again, same result.
This behaviour renders Chrome very poorly usable when this happens.
Update:
Closing any additional window, makes Chrome work smoothly again.
The same issue happens when opening a new window from the panel or from
the menu, so the issue appears to be about handling more than one
window.
Doing the same on X doesn't result in any apparent performance
degradation.
