FFT Demo stuttering / laggy visualisation on Windows 10

I have been playing around with the FFT Demo and also the AudioVisualiserComponent on windows. But in every project the scrolling animation is laggy on both of my Windows 10 Systems (also in the demo runner). I have been reading many threads on the topic, but none of them seems to address the problem on Windows. Using the OpenGL Rendering in the demo runner does improve things a little, but on one of my machines OpenGL is not supported and on the other one the animation is still flickering a bit. The issue persists at the smallest possible window sizes.
My question is: Is the JUCE-CPU rendering actually usable for those animations in a plugin or do you always have to use OpenGL (or a similar API) and write your own shaders?
