--- Comment #4 from bugg.void@tutanota.com --- I think I found the source of those names. It's https://cgit.freedesktop.org/xorg/xserver/tree/hw/xwayland/xwayland-input.c line 1544. `add_device` appends seat id to the name. It seems that the best way forward would be to update wine's detection mechanism to allow for `:`.
