Bug Description

I have updated my Ubuntu VMware vm from 18.04 to 20.04 yesterday and everything is working fine, except the animation for the launcher, which is really choppy.

If I turn on Zoom in universal access and set it to 1, then the animation works flawlessly.

Here is a screen recording with no zoom vs 1x zoom (imgur link): https://i.imgur.com/FRumzLQ.mp4

I have not noticed any other issues with animations anywhere else, nor any issues playing video.

I have `Fractional Scaling` off.

If I select `Ubuntu On Wayland` when logging in, everything is working fine.

I did not have this issue on 18.04.

Output of lspci -k | grep -EA3 'VGA|3D|Display':

    VGA compatible controller: VMware SVGA II Adapter
    Subsystem: VMware SVGA II Adapter
    Kernel driver in use: vmwgfx
    Kernel modules: vmwgfx

This is the configuration (imgur link) I have for this VM (it also has 1 gb of video memory, but even if I set it to 2gb the launcher animation is still choppy): https://i.imgur.com/8d2DbHu.png

Do you have any idea what might be causing this choppy animation only for the launcher?

Thank you!
