DataDrake just to throw that in here randomly if its okay.
The last update with 5.4 is actually the first kernel update that gave me problems on my Solus machine. The entire System "feels" unstable, some tasks don't close as fast as they used to and/or make the system "stutter" while the task is getting closed/killed.
Also I've graphic glitches in some games with this Kernel. I can't tell if this has anything to do with the Kernel or if its an Nvidia driver issue. But with the latest 5.3 kernel those problems do not happen at all. I am using a Ryzen 1700+ btw. with a 1080 nvidia.
Edit: and also the budgie-wm process has unusual very high CPU load hovers around 8% when idle and goes up to 60 or 70% when I do some simple stuff like using nautilus windows or Firefox etc. That is also the reason it seems, for the "stuttering when closing tasks" my fans go crazy because CPU load goes up like crazy and then everything slows down becaue budgie-wm process takes all the CPU.
