Instead, I could tell literally no difference. Multiple desktops works fine, scaling works fine, screen capture works fine, old apps work fine, literally everything works just fine.
Good job, KDE team.
This is Linux desktop, like if you have never had a black screen before then I'm not sure what you expect. One culprit could actually be the home .config/.cache folders that have all kind of sh*t accumulated (like why do we still do it this way? It's horrible), so I usually rename them and try again to see if this is the problem behind the scenes.
This specifically isn't the biggest issue for me right now because I use this machine mainly over ssh, but if I eventually can't do x-forwarding, RDP, or log in manually without finding some fix, that's a lot of extra work and lost functionality.
Honestly everything just worked, but using it made me so nauseous. There was some latency somewhere, never figured it out. Running Cinnamon on X11 now. I did read some suggestions to improve latency but I have PTSD so it's going to take a while before I try Wayland again.
This is with multiple monitors on Nvidia’s, all of which support vsync. Disabling that did help, but why would I want to?
Wayland, currently, is butter smooth.
Both KDE and GNOME seem to run very smoothly on Wayland.
Unless you have proprietary X server blobs, you have mostly the same low level route in either case to display stuff, so it's on the exact compositor you have tried, not on the wayland protocol.
in all other cases other than gaming and recording, Wayland has been a delight.
I could run the game on the GPU and leave more CPU for the desktop and encoder, maybe I'd be able to record and play on Wayland that way, but there's some additional drawing latency if I run the game on the GPU, the frame buffer gets sent back to the CPU before it's drawn on the display anyways.
As it's rhythm games I mainly play (ITGmania, Stepmania fork), the additional latency for getting the picture out on the display it's not really working out great for me.
For example I was a big user of devilspie for placing windows in certain locations, on certain desktops, marking windows as sticky, or marking them as different types of windows.
I am still a heavy user of pidgin (I know I know but I’ve even written my own protocols for it). I really liked being able to place it in a certain position as a certain size, mark it as sticky, put it below anll windows, and mark the buddy list as a utility window. This places in the background, removed borders, and doesn’t include it in alt-tab or window list when you do the expose type of thing. Then I had a global key binding to bring it to the front of all windows or drop it back of all windows.
As far as I know, none of these paradigms even exist in Wayland and I’ve had to deal with less useful options or completely change my interactions which is unfortunate.
I don't remember why gamma correction didn't work for me Wayland but I'll give it another try next year, maybe it got fixed by then. X11 is working perfectly well and it always did for me.
