wine fixme wait_for_withdrawn_state window

I am running a Windows execuable (.exe) using wine, in a docker container and I am dumping the graphical interface using xvfb-run. The setup is working but with some fixmes and some errors which I am trying to understand what do they mean.

The most common and fixme is:

002c:fixme:event:wait_for_withdrawn_state window 0x1004a/e00001 wait timed out
0024:fixme:event:wait_for_withdrawn_state window 0x10086/a00003 wait timed out

I found here that it means that:

Your application X Windows are possibly staying in a Withdrawn (aka limbo) state - because Wine isn't drawing to the correct X (Xvfb) Display.

However I do not understand what is this withdrawn state and why wine isn't drawing to the corrcect X. Furthermore the same fixme is present when running wine with xvfb locally without docker.

Thank you!

The whole log from the docker-xvfb-wine setup:
