Description

The window jumps, chooses some seemingly random size and location, but doesn't actually maximize. (discovered testing for #2146)

With r22104 + r22105 and the new XPRA_SET_SIZE_CONSTRAINTS=0 and XPRA_WIN32_WINDOW_HOOKS=1 switches, the xterm does maximize properly:

Summary: we get the maximized state change, send a configure-window packet to the server, and since the geometry does not match the size-constraints the server sends back a move-resize with the correct dimensions (1645x992 instead of 1648x998).

When enabling size-constraints, the differences are:

  • we fire fixup_window_style() though it doesn't make any changes
  • the geometry we send in the configure-window is already wrong:

Summary: GTK3 maximizing windows doesn't work on win32GTK3 maximizing of windows with base+increment hints doesn't work on win32

Workaround with simple test case in r22112.
