--- Comment #65 from Jan  ---
Anno 1602 works fine with the new patch. But wine terminates when I try to
alt-tab out of it. If I try to switch to the black window, it works fine. But
trying to switch to another window just make the game screen reappear, trying
to interact with it will terminate wine with these messages:
fixme:d3d_surface:wined3d_surface_blt Can't handle WINEDDBLT_ASYNC flag.
fixme:d3d_surface:surface_cpu_blt Filter WINED3D_TEXF_LINEAR not supported in
software blit. (appears several times)
X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  12 (X_ConfigureWindow)
  Resource id in failed request:  0x3600008
  Serial number of failed request:  260
  Current serial number in output stream:  261

This is using KWin on an up-to-date arch.
