This is the best summary I could come up with:
The four month old KWin merge request by Xaver Hugl to allow for triple buffering has been merged and just in time for the Plasma 6.1 code branching!
Back in December a merge request was opened against Kwin for allowing dynamic triple buffering akin to the long in-development but used on Ubuntu GNOME dynamic triple buffering.
Xaver explained in that merge request: “When it takes more than one refresh cycle to render a frame, which isn’t unheard of with weak integrated GPUs, KWin starts compositing immediately and we may or may not hit the vblank deadline.
If it’s missed, then the buffer takes a whole refresh cycle of the display to be used, which means the refresh rate drops to half of what it should be - resulting in a less smooth appearance and increased latency.
This means that if the GPU can’t keep up, latency will be increased just as much as is needed instead of almost one entire additional frame of latency and the halved refresh rate.”
Immediately prior to the Plasma 6.1 branching, it was merged.

So, now plasma is going to be even faster? Damn. It’s already butter.
Except for the overview transition, which is more like sharpened gravel.
My overview transition is seamless running X11.
That’s probably a laptop only issue. It’s butter on my desktop pc.
Yep, i have the same. But yeah, other than that, damn smooth
The amount of awesome new stuff being developed for Plasma lately is an absolute blessing. What a great time to be enjoying it
As an aside, can we get back into desktop cubes again? With all the upheaval in Windows land it’s the sort of eye candy that can win over new Linux users.
.
Cubes are back in 6.
When I showed my daughter the page with the effect settings she fell in love. She never uses the virtual desktops but we had to increase the numbers of desktops for the cube.
Is this gonna fix the stuttering when I open the overview?

Yes. Unfortunately I’m on a laptop so I can’t just keep a high-speed secondary SSD plugged in at all times. If I knew the specific file that’s being pulled I could probably sort out some ramfs stuff but I’ve never done that before.
I bet it’s
~/.cache/plasmashell.I’ll look into it
