High GPU usage when mouse move

[lfdominguez]

Hi, I experiencing something strange, my NVIDIA usage when the mouse is quiet is almost 0%, when I start to move the mouse and continue movement is reaching like 30 or 40% of usage. Tested with hyprland option of no_hardware_cursor in false and true, my monitor is 3440x1440@160Hz, tested with 160Hz and 60Hz same behavior.

On these images when the graph turn down is when the mouse is quiet. I'm using a bluetooth connected mouse (low polling rate) Logitech Anywhere 3S

I posted on #12107 as well. But here a re-upload of the same issue.
I noticed lag on Omarchy for a long time, but didn't know what was causing it. So I can't really pinpoint which hyprland version is the culprit.

The FPS drop from 100 to 30.
I don't think it is related to cursor. I tried to switch focus on keyboard, and could reproduce the same behavior.
Tried to remove animations, but didn't seem to have any effect.

Note: I notived that unlike @lfdominguez, my CPU is intel, not NVidia. So it means it's probably not a driver issue.

[gulafaran]

if @gulafaran rebase it, I can give it a try.

rebased, i do have a detail or two to work out in there. which is why its marked as draft.

[NicolasDorier]

@gulafaran tried your branch, doesn't seems to change anything

@lfdominguez can you remove "NVidia" from your title, this isn't a NVidia related issue.

[lfdominguez]

@NicolasDorier Ok, set Nvidia because is my hardware, but as you guys proved is general.

[leiserfg]

It happens to me as well (AMD igpu).

[NicolasDorier]

It may not even be related to mouse. Just opening the app LocalSend make the GPU 10%+ just because of a simple animation.

[Markus328]

Is this one (moving the mouse take a lot of GPU) normal #13902 (reply in thread) ?

I'm just a bit baffled that modern GPU can render millions of polygon calculate lighting in real time, 300 times per second without sweating, but need 10% effort to render a rotating loading icon from a random app :p

You are lucky, in my intel iGPU it would be 30%-40%. Anyway I dropped Hyprland because stuff like this

[leiserfg]

It's not animations. I opened nvtop in kitty at fullscreen (so no transitions or weird shit) and if I keep moving the cursor the GPU keeps over 30%. I'm not using blur, nor transparencies.

[leiserfg]

It seems to happen when there are other windows in the same workspace (even if they are covered by a full-screen one).
Like two kitty windows in the same WS, both not miximized GPU ~3% when moving the cursor.
If I then make full-screen one of the two, then GPU goes to 30% and stays as long as I keep moving the cursor.

[lfdominguez]

For me, NVIDIA, only 1 window (kitty with nvtop) same behavior... But is something like a loop, rise high the consume, go down, ramp up, ramp down......

Other thing, I tried to do little circle with the mouse and the consume in this case was constantly, strange behavior

[NicolasDorier]

As my laptop was stuttering too much, making it unusable but for browsing. I've tried to change to kde plasma, but it was stuttering as well, so I am not 100% sure it is hyprland related.

Anyway, I've ditched my Thinkpad Carbon X1 Gen 12, in favor of a gamer's laptop (Razer Blade 16)

My computer is usable again, the mouse is still causing the GPU to go up, but at least I'm not stuttering anymore.

I'm currently debugging this issue and trying to bisect it.

What I'm running:

• hyprland v0.54.3 to v0.55.2
• OS: NixOS
• GPU: 2x Nvidia RTX 4090

I've finally found a snapshot where this is stable and so happens to be the last time I went from 6.19.11 -> 7.0.2. I wonder if that's the issue. Will respond here with updates.

[GodTamIt]

Hmm, what's really weird was I was having trouble with this after an upgrade to v0.55.2. I thought it was just the version change but downgrading v0.54.3. Specifically, I was seeing GPU usage spikes up to 100% when opening new windows or moving the mouse -- so much so that the computer would eventually crash.

So when I posted this message, I found a snapshot that finally was stable, so I suspected it could've been due to some change in the kernel going from 6.19.11 to 7.0+ but that wasn't quite it.

I was able to get the latest v0.55.2 + kernel v7.0.9 working by switching away from a uwsm-launched Hyprland. I'm still seeing spikes to ~25-30% when moving my mouse or changing workspaces but at least it doesn't crash 🤷

[lfdominguez]

This is getting works... now even with mouse quiet....
