  1. Start OpenTTD in windowed mode. Move the cursor out of the window so that it switches to the normal desktop cursor.
  2. alt-tab so that another window covers the OpenTTD window.
  3. Move mouse cursor back over where the OpenTTD window would be.
  4. alt-tab so that OpenTTD is once again on top and focused.

At that point there is no visible cursor, although the game continues to respond to it fine. Moving it outside the window and back in again fixes it.

Reported version: trunk
Operating system: Linux

Does it happen also with Allegro? (./openttd -v allegro , you may need to recompile OTTD with --with-allegro )

Allegro doesn't hide the cursor in step 1, when moving out of the window.

This problem is reproducable on Debian with XFCE. It is not reproducable on Gentoo with KDE (3.5/4.3). As such the bug is not in OpenTTD but in either libsdl, the window manager or the combination of libsdl and the window manager.

What basically happens (from OpenTTD's point of view) is that libsdl doesn't tell that the mouse entered the window. As such OpenTTD isn't aware of that and it won't draw the mouse.

Rubidium closed the ticket.

Reason for closing: Won't fix

It's a bug in the SDL library or it's interaction with the window manager. Nothing we can do about.
