Hi All,
I have been using xpra lately, extremely cool utility.
My platform: Linux kubuntu 14
xpra version: v1.0.12-r19800
Some issues i've encountered that are worrying me:
1) After *successfully* performing 'xpra start' or 'xpra attach' I see some
error messages printed to console. Since most of the functionalities are
working fine I can't tell whether these errors are critical or not. This is
the console output after using 'xpra attach':

2) I have a GUI application that embeds a attached xpra session. When I
close the GUI application I am getting the following output - keep in mind
i don't detach from the xpra session that's embedded in the gui application:

---------------------------------------------------------------------------------------------------------------------------
The Error: OpenGL backing is not realized, as you see, keeps being sent to
console and stops only if I run the command 'xpra stop' and shutdown the
server.
Also, I have been performing the mentioned operation (closing gui that
embeds attached xpra session) for quite a while but only today I am seing
the "OpenGL backing is not realized" message. Very unusual.
Do you have any input on these matters?
Your help is highly appreciated.
*Cheers,*
*Yonatan*
