hello, yes, the ortho was buggy and fixed. But the old behaviours is still possible if you send a "compat" message. See help file.
I see, thanks. I should have checked the help file in the first place.
But how can someone use the full window area with the new default mode?
changing the windows perspective!!! (using the perspec message to gemwin, see help file)
Sorry, I don't understand. Maybe I simply don't understand which question this answers.
I guess Cyrille want to say that you can manage the clipping of ortho with the message 'perspec'. 'perspec' seems to work for the frustum (with perspective) and ortho (orthographic mode). I can't test here because, like you in your video, [ortho] not work properly on my system with a recent Gem (ver: 0.93.git 10759c2). Using [ortho] on a square in the center of my gemwin, move this square elsewhere. I can also confirm that message 'compat' do nothing here.
However, you can simulate [ortho] if you need it now with :
[GEMglMatrixMode GL_PROJECTION] | [GEMglLoadIdentity] | [GEMglOrtho -1 1 -1 1 1 20]
With these objects, you reset the projection and use orthographic projection for your geo. -1 1 -1 1 1 20 are the clipping volume in ortho mode.
Don't forget to use just after your geo (if you want your perspective come back) :
[GEMglMatrixMode GL_PROJECTION] | [GEMglLoadIdentity] | [GEMglFrustum -1 1 -1 1 1 20]
Hope it helps. ++

Why is there a limit?
what limit?
What I am experiencing when using [ortho] is that only the lower left 500x500 pixels of the gemwin can be used for rendering. Also, the center seems to be in the middle of this 500x500px area. This is with current master (cc0d464a) on Ubuntu 16.04 with a Intel graphics. Please check this screen recording:

"ortho" change the way objawayect appear smaller far away.
This I understand. All parallel lines appear parallel in orthographic projection.
It also use to change the perspective and was in conflict with the gemwin "perspec" message.
This I don't understand.
the conflict have been removed.
I'm a bit confused whether I hit a bug or if there is some big misunderstanding on my part. Can you check the above video and tell me if you get the same?
BTW: the 'compat' method does not work for me. No matter whether I send 'compat 0' or 'compat 1', the rendered output looks exactly the same.
