--- Comment #57 from Shmerl shtetldik@gmail.com --- Reverting commit 0832b5cded389096dcf74ac93367ae4ee4b8d35b and applying the workaround patch, prevents the freeze.
See https://source.winehq.org/git/wine.git/commitdiff/0832b5cded389096dcf74ac933...
Somehow that call to append_transform_feedback_skip_components inserts a varying that still falls through to the freeze condition (and workaround isn't applied since at least some varyings are present).
Józef Kucia: Can you please investigate?
