Broken lock-screen wallpaper, stutter after resuming from hibernation

[Removed by request]

Very similar to Bug #1809407 (https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1809407).

I set up my swap partition and tested hibernation on 19.04 /w Nvidia drivers.

Basically I observed 2 things:
- Lock screen wallpaper gone (black screen with clock), same as with #1809407
- Desktop wallpaper seems okay
- Big frame rate drops (despite performance governor), everything seems quite laggy

I'm new to Linux/Ubuntu, if you need any logs please tell me the commands and I will attach them.

Thanks

@vanvugt

I just want to clarify that I'm indeed talking about hibernation, not suspend-mode.
Thanks.

Thanks. It's the same bug in this case.
