Nevermind, I can reproduce. At least sort of - it works correctly on my 60Hz
laptop (exactly 60fps) but on my desktop (120Hz display) I also only see
58-59Hz. Making the window fullscreen and back to windowed makes it work
correctly as well though. When I resize the vkcube window it's random whether
or not the refresh rate fits or not.
This 17ms constant is where the 58-59fps comes from:
https://gitlab.freedesktop.org/xorg/xserver/-/blob/master/hw/xwayland/xwayland-present.c#L47
So either Xwayland gets no frame callbacks or it ignores them. As glxgears is
not affected (at least for me), I think it's safe to assume that the bug is in
Xwayland. I opened https://gitlab.freedesktop.org/xorg/xserver/-/issues/1309,
