It looks like the kind of resizing that happens when the system scaling
factor is changed, or when the window is dragged between two monitors
with different resolution scaling factors (e.g. 96 pixels per inch vs.
150 pixels per inch). I think that Rgui.exe currently does not perform
any resolution scaling on its own; it seems to rely on the bitmap
scaling provided by Windows for "non-DPI-aware" applications.

How many monitors do you have and what are their resolutions? Are their
connections reliable? It could also be something having updated in
Windows 11 itself.
