which rendersystem are you using? works here for me

[sercero]

OpenGL 3+, you'll see that my latest screenshots were partially showing the UI.

Also, this double renderOneFrame() is present here:

ogre-meshviewer/ogre_mesh_viewer.py

Lines 739 to 740 in 449c1cc

	self.getRoot().renderOneFrame()
	self.getRoot().renderOneFrame()

[paroj]

it seems that our imgui code lags behind by one frame. I would like to investigate this first, before adding this workaround

[paroj]

imgui does not seem to lag. please try again, whether latest master fixes the issue

OK, it'll take me a while because I never built OGRE with python support.

Lets see how it goes...

oh, I meant meshviewer master. The changes are on python side.

Also, for ogre the master SDK includes the python bindings:

Oh, thanks.

Yes, I saw in create_win_package.bat that you download that package but since it was "master"....

No problem now I understand.

[sercero]

Yes, now it works.

Thanks.

FYI the issue was that we were downloading the image from the backbuffer after swap buffers. This is platform specific and can result in an image that is 2 frames old.
