Comment 1 Nate Graham 2023-09-02 04:32:50 UTC 
Is this really a Qt6 issue? I can reproduce it in Plasma 5. See Bug 455780 and Bug 459467.
Comment 2 Fushan Wen 2023-09-03 04:19:51 UTC 
Yes, the fps is signification lower than Plasma 5, on both X11 and Wayland
Comment 3 Nate Graham 2023-09-06 21:48:16 UTC 
Interesting. For me it's no worse on Plasma 6 Wayland than it was on Plasma 5 Wayland.

Merge desktop grid and overview together with a new three-state design

Merges the desktop grid and overview effects together in a new three-state one;
you can switch between them with a certain shortcut or gesture, and you can also
still access either the desktop grid or overview directly.

Default shortcuts are also updated to be Meta+G for Grid, Meta+W for Overview,
Meta+Tab to switch between the three states and Meta+Shift+Tab to cycle in the
opposite direction.

Comment 5 Fushan Wen 2023-09-28 13:47:47 UTC 
Not fixed, and becomes worse after the new overview effect is merged.
Comment 6 Prajna Sariputra 2023-11-03 04:13:55 UTC 
I think I'm also experiencing this issue, I also see the `amdgpu: amdgpu_cs_ctx_create2 failed. (-13)` error messages while triggering overview/desktop grid combined effect, and the animations (especially concerning the desktop grid) feels rather choppy, certainly more so than in Plasma 5.27.9.

I compiled Plasma 6 using kdesrc-build, KWin is currently at commit abf642d42e8189deaabf1999661e83aab25b99fa in the ~/kde/src/kwin folder, and my GPU is the AMD Radeon 680M (integrated with the AMD Ryzen 7 6800H), with Mesa 23.2.1, kernel 6.5.9, Qt 6.6.0, on Arch Linux. I also only tested with Wayland for now, so not sure how it looks with X11.
Comment 7 Prajna Sariputra 2023-11-04 08:40:54 UTC 
Turns out that the issue I am seeing is in fact a different problem, specific to touchpad gestures and the animation speed setting, I have filed bug 476536 for that, apologies.
Comment 8 Fushan Wen 2024-01-02 16:35:51 UTC 
Recently the performance has become better
