It does not trun black, but it shows blueish desktop color and program-on-top disappears. And even on Win10, if the mouse cursor acrosses the SDL window border, windows inside SDL window disappear and re-appear(like flashing) and sometimes they doesn't re-appear.

Before reporting the bug, I discovered that boxedwine.exe can run on Windows XP by changing OS Verion and SubSystem Version in boxedwine.exe's PE Header. And the program running inside boxedwine disappears and re-appears within Boxedwine SDL window from time to time.
I don't have old ipsw in hand but IIRC they are similar to zip.
7-zip can open new ipsw (link above) but main partitionn (largest dmg) contains APFS which can't be opened with 7zfm. Instead, 7zfm shows partition list.
seems to be a bug in r4002 and now is fixed by r4049.
iOS 11 will use APFS for system partition. http://appldnld.apple.com/ios11.0/091-31750-201700919-35B0766C-9027-11E7-9375-2F35B64D2808/iPhone10,4_11.0_15A372_Restore.ipsw
I have nosound=true and sbtype=sb16 in dosbox.conf, when I change nosound=false and everything goes fast again. So nosound=true is root of this problem.
