Also, it sounds like you are using fractional scaling. If so then please
try scale 100% or 200% instead. Fractional scaling is expected to
underperform:

Title:
Desktop runs at low frame rate
Status in xorg package in Ubuntu:
New
Bug description:
Moving windows around and using the launcher results in low frame rate
(<20 fps), instead of moving smoothly (~60fps).
I don't have this issues when I watch videos on YouTube, but I find
that the problem is common in all the GNOME-based distros I tried
(Ubuntu, Fedora, Clear Linux). Also, the cursor runs smoothly without
issues.
I'm running Ubuntu 19.04 (with the default updated packages) on a
Chuwi 12.3 LapBook with an Intel Celeron N3450 and 6GB of RAM, at 2736
x 1824 pixels of resolution.
In addition I directly filed a bug on the GNOME-shell issue page
(https://gitlab.gnome.org/GNOME/gnome-shell/issues/1237).
