Created attachment 60161 [details] Irfanview 4.44 under Wine 3.0-rc5 on openSUSE
Adding a screenshot from my system, openSUSE Leap 42.2, in which it works.
Artem, maybe the problem you're still seeing isn't in Wine, but some difference in our host systems?
Have you moved the about window or overlaid it with something? It works that way. It won't work once you invoke it without doing anything else. Also your composite window manager might have interfered - I don't use one.
