I am running Ubuntu 21.04 VMs in VMware Workstation Pro 16.1.2 build-17966106. When toggling between full screen and normal mode (which causes VMware to poke the guest tools to change the virtual monitor resolution to adjust), the VMs forget their UI scale, resetting back to 100%. The Windows 10 VMs do not exhibit this behavior, which suggests that the problem is not the hypervisor or the hardware.

Any thoughts would be appreciated!
