Editor freezes sometimes when waking up from suspend

[Tooniis]

Godot version: 3.2.2

OS/device including version: Arch Linux (kernel version 5.8.3-arch1-1), GNOME 3.36.5

Issue description:
Sometimes after suspending the machine then waking it up, the editor freezes completely, and when killed, becomes a zombie process.

Steps to reproduce:

1. Open the editor and use it for some time
2. Suspend the machine
3. Wake it up and log in
4. Editor is frozen
   I haven't yet been able to figure out the exact circumstances required for this to happen. It seems random so far.

Minimal reproduction project:
Any project will do.

Which graphics card model (and driver) are you using? Also, can you reproduce this with any other 3D games or applications?

On Linux, suspend tends not to be very reliable on NVIDIA hardware in my experience.

AMD Radeon R5 M330, with the amdgpu kernel module and Mesa 20.1.6
