We are experiencing a similar bug with Magic Online (.NET based) *using
Cinnamon*: the position of the window regularly jumps to a fixed position; and
when maximized steals the focus.

In the join the output with WINEDEBUG=+x11drv, you can see what is happening
with wine 5.17:

As reported in a previous comment, reverting to the commit prior to
c5ec1585f6e5211a2b63e3435748210552250534 fixes the issue.

This bugs seems related to the Cinnamon WM, no problem with the other WMs I
tested with (unity and xmonad); it could be interesting to try with gnome shell
or related WMs.
Switching wine to "emulate a virtual desktop" workarounds the issue as well.

It is sufficient to run wine 5.17 in a virtual machine with Ubuntu Cinnamon
installed to reproduce the bug with Magic Online.
I'll be happy to try patches or provide other debug traces, just let me know
what may help tracking down the issue.
