Unity editor window not rendering properly when switching tags

[mergipe]

Output of awesome --version:

awesome v4.3 (Too long)
• Compiled against Lua 5.3.6 (running with Lua 5.3)
• D-Bus support: ✔
• execinfo support: ✔
• xcb-randr version: 1.6
• LGI version: 0.9.2

How to reproduce the issue:

1. Open the Unity editor from Unity Hub (I'm on Arch, installed it from the unityhub AUR package).
2. Switch to another tag.
3. Switch back to the Unity tag.

Actual result:

Most parts of the window become transparent and are only rendered properly after passing the mouse over that area.

Expected result:

The window should be rendered normally.

Additional information

I'm using picom, but disabling it did not make any difference. I also tried using the default rc.lua with no success.

@mergipe As a fellow unity developer, I can suggest to use this workaround. Worked for me.

Thanks, it worked!
