Re: Bugs in gui/back

Hi Fred,

It is easy to inspect these numbers as GNUstep stores them on the root
window as properties.
 xprop -root _GNUSTEP_FRAME_OFFSETS

I typed this command in the shell I use to start the app directly after a reboot of the machine. It said

_GNUSTEP_FRAME_OFFESTS: no such atom on any window

I then started the app for the first time after a reboot and reexecuted the above command. It then said

_GNUSTEP_FRAME_OFFSETS(CARDINAL) = 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0

Every group of four values belongs to a window style. If you see zeros
or negative values here this might point to invalid numbers. In that
case you should remove these values with the following command:
xprop -root _GNUSTEP_FRAME_OFFSETS

That's the exact same command as above? Is this correct?

And start up a GNUstep applications, which will then try to recompute
the values. If we are lucky this will already remove the issue. If it
persists I will have to investigate a bit more what is going on.

Unfortunately this had no effect. The app still misbehaves. :-(

Starting the app gives

Grabbing the corner of the window (not yet significantly resized) produces
