Ghost Window with BGB on Wine

[Near1980]

This seems to be partly an issue of Wine/BGB but given IceWM 1.3.8 and Xfce4 appear to handle it better than the latest git version I'm reporting it here.

System: Debian 8 x86.
BGB is a Game Boy emulator/debugger : http://bgb.bircd.org/

To reproduce:
get Wine and BGB
Wine option "Let the window manager control / decorate the windows" should be (obviously) set.
Run BGB.

• Right click > Options
  • Graphics > Output > set to Directdraw
  • Misc > Enable show framerate
• Rigth click > Load ROM > Load the bgbtest.gb ROM
• Minimize the window and restore it

Two windows should appear at the taskbar, one of them blinking. First of them appears to be a BGB hidden window and the other one the actually shown window.
By fiddling around with options menu and opening/closing the debugger (ESC Key) it will eventually disappear until it gets minimized and restored again. When it disappears, it can be found at the Window List menu.

Under IceWM 1.3.8 such window is always hidden from the taskbar. Same applies for Xfce4.

1.3.8 is no longer maintained as it is from 2013 and released by others. Since then there were a number of major releases. You can look at #304 for pointers or follow the instructions on the IceWM website on how to install the current software, which is stable and recommended.

I'm sorry I didn't explain it clearly enough.
I'm running IceWM 1.4.2.1675. This is the version where this bug is happening.

My system offers IceWM 1.3.8 from the package manager. That's the version I have updated from and where this bug didn't happen.

Ah I see now. Can you try and see if xprop and xwininfo on that window show anything? Ah bgb.exe works. xwininfo -tree -root shows 2 windows. One has size 1x1. xprop on the other bigger window says that the 1x1 window is the group leader. The 1x1 WM hints says the program specified location is -4,7, but the actual location is 0,7. So somehow the window wanted to be offscreen but is onscreen. That might explain its button on the taskbar.
