Yes, this is a message from the Mesa Vulkan driver for Intel hardware, and
there isn't much that GTK can do about it other than not using Vulkan.

If the Vulkan renderer has enough problems (#1081957 is a more serious
one), a possible workaround in GTK is to switch the default back to one
of the OpenGL-based renderers.

In the short term, if you consider this to be a serious problem, please
use environment variable GDK_DISABLE=vulkan or GSK_RENDERER=ngl
(or GSK_RENDERER=gl or GSK_RENDERER=cairo).
