I'm not sure how Xwayland communicates the scale info to apps, but
adding a xorg-server task anyway. Because that's the source package of
Xwayland.

Title:
XWayland applications respect scale only if a scaled output is primary
on a mixed-scale setup
Status in mutter package in Ubuntu:
New
Status in xorg-server package in Ubuntu:
New
Bug description:
The bug occurs with any XWayland application. I tried VSCode, Chrome,
Audacity, Darktable...
I have two monitors with a different DPI. One is 4K HiDPI monitor and
the second in LowDPI 2K monitor. I can setup 200% scale for a HiDPI
monitor and 100% scale for a LowDPI. All native gnome applications are
fine.
The bug: when I select LowDPI monitor as a primary, XWayland
applications stop scaling on a HiDPI monitor. They run 100% scale on
both monitors. If I select HiDPI monitor as the primary, XWayland
applications scales 200% on both monitors.
