KDE Run Command won't display well after continue from suspension

After continue the VM from a suspension, KDE's Run Command won't show up correctly, it looks like this:


It sometimes show up like this as a block box, or red box, or blue box, or a transparent box. The only way to fix it is to reboot the guest OS. But the problem comes back as soon as I suspend it. I'm wondering if anyone is having the same problem or if anyone know a solution to fix.
This happens on both Debian (stretch) and Arch Linux.
The problem happens on both parallel 12 and 13
I'm using macOS 10.12.6 on MacBook Pro 2016 with Touchbar 15inch.
