Mojave dark mode - Font bug

Hi, I recently update my mac mini from High Sierra to Mojave.

When i have Light Mode everything is perfect, however in Dark Mode font smooth.

I recorded video, which is showing problem. As you can see in 10 sec of video font in hover is ok.

Current bug is more visible on light wallpaper.

I recommend to resize your browser for smaller window and set up video speed for 0.5
