Gui shadows broken after upgrade to PD16

[VladA]

Ubuntu 16.04 vm with PAralells guest tools installed
Parallels desktop for mac15 - everything is fine
Upgrade to Parallels desktop for mac 16, instead of shadows , there is just black squares
parallels guest tools update changed nothing for pd16.

I got the exactly same issue after upgrade to from pd15 to pd16
But I found a workaround to solve which is turning off the 3d acceleration at the advanced settings inside Graphics tab.
Also I keep getting a message from PD tool to ask me log out for coherence mode, which I don't use and log out also doesn't help stop the message for each reboot.



Mine is MacBook Pro (15-inch, 2017), macOS Catalina 10.15.6
Linux ubuntu 4.13.0-45-generic #50~16.04.1-Ubuntu SMP Wed May 30 11:18:27 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
And we are using Business edition.

having the same issue 18.04 and 20.04 is fine but 16.04 graphics drivers seem to be broken

Here is a workaround for now:
sudo apt install compizconfig-settings-manager
Now launch compizconfig-settings-manager, click Ubuntu Unity Plugin, Decorations tab. Enable "Override Theme Settings", now set the Active and inactive window shadow radius to 1 (minimum setting) and set the shadow x and y offset to 1 (minimum). It doesn't fix the window text but at least usable.

Alternatively, a better option may be:
sudo apt install compizconfig-settings-manager
Launch compizconfig-settings-manager
Under OpenGL, disable "Framebuffer object"
This retains the shadows and fixes the window text!
