[kwin] [Bug 455585] WindowHeap-based effects' animations aren't smooth when using a high refresh rate screen
https://bugs.kde.org/show_bug.cgi?id=455585 --- Comment #48 from 1...@mailbox.org --- Oops, accidentally submitted trying to tab. Overview: - Opening and closing clearly runs at 60fps (comparing it to my 60hz monitor right next to my 165hz one), while Show FPS shows minimal frame drops - Switching workspaces in the overview at 60fps. - Dragging a window moves and resizes the window at the correct framerate, releasing it makes the window "jump" back at 60fps. - There is no stuttering. Were my display 60hz, I would consider this effect very smooth. Grid View: - Pretty much exactly the same as the overview including the thing with window dragging. New Edit Mode: - Opening and closing runs at 60fps (probably), but has more general stutters than the other effects. It seems like making my panel non-floating made it a little smoother, but it's inconsistent. - Opening the panel settings where it opens the window and moves the desktop out of the way to make space runs at the correct framerate. - Opening the "Add Widgets" sidebar also pops it into view at the correct framerate. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=455585 --- Comment #46 from breakingsp...@gmail.com --- Still an issue for me, 1440p144hz on RX 580. Confirmed the issue has been persistent since Plasma 5, with the snapping workaround no longer viable in 6. I do not believe this is a performance bug, when it worked in 5.x it was quite smooth and did not seem to particularly hit system resources. Every other kind of transition Kwin uses (virtual desktop slide) are smooth and buttery while. Doubling down on the old workaround and how it can probably help: After quick-tiling the first window in a 5.27.5 session, the Windowheap refresh rate would sync up for the whole rest of the session. If this wasn't done, the effect would seem to be locked at 60fps. Whatever routine or check was part of that quick tiling operation in 5.x, I'd be willing to bet it will work in 6.x if we call it explicitly. -- You are receiving this mail because: You are watching all bug changes.

If I remember correctly, one core jumps to 100%. I run on a 3440x1440 display with 75hz.

https://bugs.kde.org/show_bug.cgi?id=455585 --- Comment #41 from rjawiygv...@gmail.com --- One thing that makes it sound like it's not a real system slowdown is that "show fps" desktop effect still shows 140+ fps during animations. Also while I was trying to confirm this again on X11 just now everything was working perfectly smoothly! But then I logged out and logged in and it's back to "60fps" again. So far I have no idea what could have temporarily fixed it. Turning on the fps counter wasn't it, and running a fullscreen game that I played during previous session which restarts the compositor cause it's off when the game is running also wasn't it, not was suspend. -- You are receiving this mail because: You are watching all bug changes.

Feels more like actually bad performance in the effects themselves, like they're doing too much while animating and slowing down the system. It wouldn't be the first time that exact thing happened, and we fixed a prior occurrence of it already. FWIW I can still reproduce this issue a bit with my hardware (HD620 iGPU + 4K screen @ 225% scale). It's nowhere near as bad as it was before, and quite tolerable now.

https://bugs.kde.org/show_bug.cgi?id=455585 --- Comment #39 from rjawiygv...@gmail.com --- I'm still at 6.0.5 but I switched to x11 because wayland breaks some things I currently need to run, and I remember reading somewhere that triple buffering was already enabled on x11 which means animations should be smooth, but they actually work exactly the same as they do on wayland, most animations are smooth but overview looks like it's locked to 60hz. -- You are receiving this mail because: You are watching all bug changes.

And in general moving windows around or switching workspaces behaves as expected. But overview animations look like they run at 60 fps, while "show fps" still always reports 144 fps. However, dragging windows within the overview is done at 144 fps. The only animations that are locked to low framerate are opening the overview and moving between workspaces in the overview. -- You are receiving this mail because: You are watching all bug changes.

What's interesting this time is when I drag any window in Overview, it moves with the cursor at the expected full 100 FPS until I release my mouse button. I've also upgraded my GPU from a Radeon 570 to a Radeon 6750 XT since the previous comment while keeping the same 100 Hz monitor, so I'm still using the same AMDGPU graphics driver. I haven't tested it on X11 but getting this fixed for Wayland at the very least would be great, since it's the path forward for windowing systems these days.

Here I slowed the original footage from 100 FPS to 60 FPS using Avidemux and reencoded it to make the file size fit below the 4MB limit. If you look through the video frame by frame, you'll notice that there are missed frames in the transition going in and out of the Overview effect. Every 2-3 frames appear to be a duplicate of the previous one, which indicates that the effect ran about 60 FPS instead of the expected 100. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=455585 --- Comment #30 from breakingsp...@gmail.com --- Confirmed that this is still an issue for me as well on 5.27.9, and that the steps in https://bugs.kde.org/show_bug.cgi?id=455585#c25 do work to correct the framerate on these Windowheap effects. I didn't realize this was the fix until the recent comment, my workflow always involved tiling windows like this within the first few minutes of a session. This is the old "Workspace Behavior -> Screen Edges -> Tile: Windows dragged to left or right edge" behavior, to note. Now it makes me wonder if there's a line or function in that tiling code to check the monitor refresh rate, which could affect other effects. -- You are receiving this mail because: You are watching all bug changes.

I'm encountering this in 5.26, while 5.25 did not seem to have this problem for me. After starting Kwin, the Windowheap effects are choppy, and after a few minutes it corrects itself, I can't tell yet if a certain action causes it to sync up, or if it's simply time. This can be reproduced by simply restarting Kwin in-session. Interestingly, i'm only encountering this in my personal user profile and newly-created test profiles, while my existing work user does NOT encounter any choppy animations/framerates at all. I can restart Kwin in the work profile, all effects are seemingly 144hz as usual. I want to look over config/cache in case anything there is a factor, as the two profiles should have an identical Kwin config (aside from window rules and related). -- You are receiving this mail because: You are watching all bug changes.
