I can replicate the issue but only when using the options you supplied: -display gtk,gl=es,zoom-to-fit=no -device virtio-vga-gl,xres=1680,yres=1050 If you leave it at default settings it doesn't cause glitching.
There are some other scenarios that might reproduce this as well, Like the "Pairing" progress screen from bluetooth wizard
