Hi list,
Until now, and as far as I (think I) can remember, GEM was rendering frames even if the window (with or without border) was :
- out of the screen
- reduce in the tool-bar
- hidden by an other window
The last time I use this property was on an Ubuntu 13.10 both with "pd-vanilla + gem from the depot" and " pd-extended" (but I can't give you versions... because... well, I don't know them... sorry)
On several different patches, I recorded GEM content (which was not display on my desktop because of "offset" option) with the combo [pix_record] / v4l2loopback in order to make a "fake webcam" to stream. It was working. It is still working on computers where those patches where installed.
Now, I am on Ubuntu 14.04 / GEM: 0.93.3 and if anything is put over the GEM content, it seems to be that none of the pixel "under" is rendered.
If I open the v4l2loopback device on VLC (or whatever) and hide part of the GEM window (even by dragging icons from my desktop), those parts are not refresh anymore.
Does GEM change its way to render ? Is the Ubuntu 14.04 display different ? Do I misunderstood something ?
Sorry if I'm fuzzy... If questions, I'll try to explain better.
Thanks in advance for any help.
