--- Comment #1 from Armin Altorffer aapmak@gmail.com --- 1.7.50 will exhibit the shame behavior from Heroes of the Storm; I tried it with and without Pulse Audio (pasuspender & winetricks sound=alsa), makes no difference (Pulse Audio has demonstrated to sometimes cause issues in some applications run in Wine).
Still crashing on close. The interesting detail being that it takes some time for it to crash; almost as if somehow Heroes of the Storm is making a certain call (unknown if IO or something else) and that simply times out and then it crashes.
