[kwin] [Bug 480885] High CPU usage for window under cursor \ plasma shell (if over desktop) and kwin_wayland when moving mouse cursor
https://bugs.kde.org/show_bug.cgi?id=480885 --- Comment #21 from Dashon --- Created attachment 170524 --> https://bugs.kde.org/attachment.cgi?id=170524=edit Video of htop taken on my phone. Here is one more video, but taken on my phone. As mentioned before, when other cpu intensive tasks are running. The kwin_wayland process doesn't use as much cpu. In this video, you will see the kwin-wayland process using more cpu than the main firefox process while I am trying to watch a video. That is despite hardware acceleration being in use. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=480885 --- Comment #20 from Dashon --- Created attachment 170512 --> https://bugs.kde.org/attachment.cgi?id=170512=edit Screen Recording of htop as I move the mosue around. kwin seems to use less cpu when another cpu intensive process is running, but this screen recording should still show the spike that is happening. In general, I notice kwin using more resources cpu and gpu when moving the mouse, windows, or watching videos that say gnome or xfce. This lead me to believe that there may be some kind of performance issue lurking about. On the aforementioned desktops. There respective compositors' do not use enough resources to make it to the top of various resource monitoring utilities such as htop or intel_gpu_top in most cases. For this reason, I am extremely interested in debugging this issue further. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=480885 --- Comment #18 from Dashon --- Well it looks like the file generated by hotspot is too big, so for now I'll just post screenshots of the flamegraph. If there is another way to send you the perf.data.perfparser files then let me know and if there are any other logs you need. Let me know too. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=480885 --- Comment #16 from Dashon --- I believe I am also seeing a similar issue where moving the cursor or really any kind of movement seems to cause spikes in cpu usage for the kwin_wayland process. I especially notice this during video playback during firefox. I have downloaded the appimage for hotspot and I'm not sure if I did everything correctly, but I will try to save and submit the file it produced when I attached to the kwin_wayland process. During the test I mostly triggered the overview, moved the mouse, and scrolled through the desktops. I'll do another test with video playback in firefox and then submit that later.

https://bugs.kde.org/show_bug.cgi?id=480885 --- Comment #12 from feat...@engineer.com --- Hi, I'd really like to help figure out why I'm seeing this increased CPU usage, but I couldn't figure out how to make perf show the relevant binary name and function name... Even when adding the debug info server, I wasn't able to see it in hotspot. I would appreciate it if anyone could help me setup my machine to be able to debug this properly. -- You are receiving this mail because: You are watching all bug changes.

If you can consistently see this high CPU usage, you could try finding out what's causing it in kwin with hotspot (https://github.com/KDAB/hotspot). Just record a trace of the kwin_wayland process, and check if any single function call looks conspicuous in the flame graph. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=480885 --- Comment #3 from feat...@engineer.com --- With regards to the increased kwin_wayland cpu usage on my latest reply (as compared to my first one): it stemmed from the fps desktop effect - when I turned it off, the figures returned to the ones I have reported initially, that is to say, the nvidia driver didn't make it worse (nor better). -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=480885 --- Comment #2 from feat...@engineer.com --- (In reply to Nate Graham from comment #1) > Does the issue go away if you use the proprietary drivers, rather than > Nouveau? No. I've installed the nvidia drivers using ubuntu-drivers, it's still using up about the same amount of CPU. The only difference is that now even on idle kwin_wayland uses 20% CPU, and nv_queue uses 15% CPU. When moving the mouse kwin_wayland now uses almost 50% CPU, the window under the cursor still uses around 20%, and nv_queue uses about 10% CPU.
