[Gate-users] Orientation of mhd file

[Jérôme Suhard]

Hi,

I can reproduce it.
Technically, my OpenGL custom commands are called one first time even in
Stored mode. At this moment, it seems that the rotation was not yet
applied.
But with X11 in Stored mode, there is no "refresh" of the graphical scene
thus leading to this artifact, you can remove it by forcing it with:
/vis/viewer/refresh

Best regards,
