[Lazarus] Gtk3 high resolution issues on Linux

[Ryan Joseph]

I'm implementing the OpenGL control for Gtk3/Linux and noticed that on high resolution display the widgets are all scaled wrong. Is this a known bug with the Gtk3 widget? I have very limited Lazarus experience so I may be overlooking something simple.

If it is something which is just not implemented correctly does anyone have any ideas of why it's doing this? Since I'm working on the OpenGL control I could try fixing the high-res scaling also.
