TiddlyDesktop messages in Linux terminal - should I be worried?

[AndrewMc]

Hi All

I have just downloaded and installed the ninth release of TiddlyDesktop (v0.0.9) on my Linux machine (Ubuntu 16.04).
I ran the nw file. This successfully opened TiddlyDesktop, but an error appeared in the terminal:

[5600:5600:1117/203400.220030:ERROR:sandbox_linux.cc(346)] InitializeSandbox() called with multiple threads in process gpu-process.

Should I be concerned at this message?

I also had a couple more messages appear:
Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.
Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.

These seem to be more like advisories and so can be ignored by me, but I am left wondering about them. Is anyone able to tell me anything about these Gtk messages?

Lastly, I will just say that (apart from these Linux terminal messages) TiddlyDesktop seems great. I have finally made a start on using TW for a couple of book translations and am really looking forward to the possibilities that TW will provide.

Cheers

I don't work on tiddlydesktop but those don't look like they are anything to worry about. Software development is always a moving target for things like this and you get messages like that as the platforms change as you are developing for them. They will probably be addressed in future updates but they don't look like anything that would affect you use of tiddlydesktop.

Thanks Jed. Yes, TiddlyDesktop seems to be doing everything expected of it so I feel more relaxed about ignoring the messages.
