Whatever you're seeing, it has nothing to do with Vulkan child window rendering. Please don't pollute this bug.
Well, duh. At the very start I've asked about a *gl* version (but - slightly different debug spew aside - gl and vulkan look roughly the same, gdi just crashes). I was just checking with you if there was perhaps some more generic problem at the lower level.
