Warnings and Errors while starting up?

[Bazmundi]

Call me crazy! I Now I don't mind hearing I am throwing the setup a curve.

I am running Debian 10 on an ye olde PC.

While it has a graphical environment I am hooking into the PC via MobaXterm.

So, that means I am using the tunnelling function to display the WhiteCAT IDE on my windows laptop.

When starting WhitecatIDE from Debian box, in console, I get what appear to be obligatory warnings when running:

./linux64/TheWhitecatIDE

(TheWhitecatIDE:2829): Gtk-WARNING **: 22:06:59.339: Theme parsing error: gtk.css:127:35: The style property GtkButton:child-displacement-x is deprecated and shouldn't be used anymore. It will be removed in a future version

(TheWhitecatIDE:2829): Gtk-WARNING **: 22:06:59.339: Theme parsing error: gtk.css:128:35: The style property GtkButton:child-displacement-y is deprecated and shouldn't be used anymore. It will be removed in a future version

(TheWhitecatIDE:2829): Gtk-WARNING **: 22:06:59.340: Theme parsing error: gtk.css:132:46: The style property GtkScrolledWindow:scrollbars-within-bevel is deprecated and shouldn't be used anymore. It will be removed in a future version

Via a console running on a laptop talking to the Debian PC I am getting the obligatory warnings and then some, namely:

[2829:2829:0312/220659.464863:ERROR:edid_parser.cc(102)] Too short EDID data: manufacturer id
[2853:2853:0312/220701.856022:ERROR:viz_main_impl.cc(161)] Exiting GPU process due to errors during initialization
Xlib:  extension "MIT-SHM" missing on display "localhost:10.0".

The IDE is "running" but is it really? What is the likely impact of this error please?
