@valdikss it really needs its own bug report, have you confirmed the problem definitely goes away if you replace/downgrade only /EFI/fedora/shim.efi and /EFI/fedora/shimx64.efi with the previous shim? If you can reproduce, you should give this update thumbs down karma. Thanks.
I was doing a zoom with this today, and oomd keeps killing the scope the zoom is running in. Also sounds like a memory leak as xvitaly says. Should I open a bug for this? There's only one thing to go on in the logs.

That's a metricftonne of execessive resources. Nothing is logged until the kill. If I disable oomd, it consistently siphons away enough resources to freeze the computer completely - can't get to a tty, mouse arrow frozen, doesn't recover at all for 1 minute so I forced power off.
