Description:
In my application I am using the Anchor Docking and the OpenGL widget. Both seem to not work well with gtk3 (see attached screenshot).
The form with the OpenGL component renders black and sometimes flickers and briefly shows the controls.
The form with the Anchor Docking components just renders them all at the bottom of the window, the layout entirely broken.
The console is spammed with a good amount of the same error:
(ale_editor_debug_x86_64-linux:14905): Gtk-[1;33mWARNING[0m **: [34m18:08:36.868[0m: Negative content height -1 (allocation 1, extents 1x1) while allocating gadget (node scrolledwindow, owner GtkScrolledWindow)
The application works perfectly in gtk2, though. No rendering issues and no critical warnings there.
