If you connect into a macOS device and you have the 'Blank Guest Monitor' feature turned on, some applications either show up blank (see attachment) or else their window becomes frozen (though not on the device itself, because the mouse and keyboard actions still go through, but it looks frozen from within the viewer/client).
I originally suspected it had something to do with hardware acceleration, since some applications (like Finder) weren't affected, but Chrome which uses it certainly was. And hardware acceleration messes with the GPU, right? But this bug still crops up even when the hardware acceleration turned off.
I should also mention that in the case of Chrome (as in the attachment) the freezing is occurring within the tab, not the application bar or menu. So it's whatever's being rendered within the window/tab that shows up blank/frozen.
I'm on the latest stable version, v20.12.1734.7640.
