Things are slowly improving, especially as browsers themselves, especially Firefox, steadily do more GPU stuff (putting pressure on the driver makers to fix things), but there’s a reason why it’s been very rare for non-game UIs to target GPUs for rendering: GPU drivers are atrocious. Even if they don’t crash, the number of absolutely fundamental and critical bugs that they have is very impressive. As an example of a fundamental thing being broken, try https://github.com/tomaka/winit/pull/332#issuecomment-341383... and later on down in the thread where a driver update fixed it.
