Re: NSBorderlessWindowMask and NSMainMenuWindowLevel

Hi Fred

Thanks for your input. The window manager is
openbox-3.5.0_3
vs
openbox-3.5.2_1

However, the problem occurs even without window manager.

And since it works with window manager if I use software rendering (vesa) it seems like the problem should be elsewhere. Seems more like an x11 problem, how x11 handles borderless windows or something... There seems to be big changes to dri, GL etc related stuff but that stuff is not really my area...

The is onecomponent missing in your list, the window manager. This is responcible for window placement and most likely thenew one isn't fully supported by GNUstep.
