The fact that you have 3 x 4K monitors connected makes me think all those GTK warnings are some kind of texture size limit being exceeded. Although even basic GPUs should support textures up to 16K in size. Perhaps this is a GTK-specific problem where it tries to internally allocate something that the full desktop resolution and fails.
