I have Ubuntu 20.04 running MATE on a RPi 4 8GB and I have to say it is pretty damn sluggish. I need to dig under the hood more to lighten it up, because even with a quad core at 1.5ghz and 8gb ram... the window system and just general menus and movement feels slower than an old Win2K machine I had with only 64MB of ram at 266mhz. I had to enable the outline-of-window-only when moving or resizing because just moving a firefox window on the screen drops the FPS to a slideshow.

The out-of-the-box performance on the pi4 is a drag, OpenGL support has been silently crippled in many repo applications for compatibility reasons, and overclocking the sdcard is more limited than the pi2/pi3 (primary bottleneck). You may have to brute force the marco GPU flags to figure out which features are implemented, don't break video codecs, and don't conflict with kernel settings (v4l driver). There are a dozen reasons things may be glitched, but usually it is the lack of active cooling causing the pi4 to thermal throttle. Also, mate-tweak tool can save time digging for settings. Also, if it is the Ubuntu distro rather than Raspbian, than there is a lot of missing software to get things working well. Best of luck =)
