I tried disabling zRAM and just using a regular swap file. It didn't make any difference, and it kept glitching on me really bad throughout the workday. So I just found a repository with VirtualBox KMP packages that apparently syncs with the latest Kernel Stable repository: - https://download.opensuse.org/repositories/Kernel:/stable:/KMP/standard - https://download.opensuse.org/repositories/Kernel:/stable/standard/ So I'm now booted into that, and we'll see how it behaves throughout the workday tomorrow.
