Description

Seemingly randomly, Hyprland will start having hammering a single core of my CPU, causing visible lag to the entire desktop. I have to restart it to get it to stop.

Closing something like Firefox during this causes the entire desktop to freeze without swapping to a TTY or anything working, resulting in me having to power off my computer.

How to reproduce

No idea, as I've yet to encounter the reason for it. It's not uptime related, nor have I noticed a specific action that causes it. I've had it happen numerous times in a day, or it can once every week. I seem to be a magnet for these types of random hickups...

open ssh to your pc and whenever it hangs, connect via ssh, sudo gdb attach $(pidof Hyprland) and show the output of bt -full

Haven't got it on my Desktop but managed to get the core maxxing on my laptop today, which runs a much older hyprland version:

If I can get it on my Desktop today, or can get my laptop to freeze will post an updated one.

[vaxerski]

IIRC that one is fixed on git?

[LivacoNew]

As I said my laptop's running a older version so may make sense, Desktop's not acted up today yet so may be something completely different still just that was the best I had for a few days.

[LivacoNew]

Got it on my Desktop finally, happened when I closed a Firefox window. Elevated CPU usage but not pinned, from what I can tell in btop it was only about 50% on one core.

Looks like one of these lambdas, to be clear I'm not an expert in C++ just blindly following the trace back so ignore me if I'm being dumb https://github.com/hyprwm/Hyprland/blob/2b520571e897be2a0e88c8692da607b062000038/src/protocols/PrimarySelection.cpp#L13-L14

[vaxerski]

IMO it's likely you have some clipboard manager that is just going nuts

[LivacoNew]

afaik I don't even have a clipboard manager installed

[vaxerski]

grep what you have installed for clip, maybe you do

[LivacoNew]

Don't believe any of this would count as a clipboard manager..?

[vaxerski]

dont think so, odd

[LivacoNew]

Moved back up to latest git a few hours ago fixing some flickering in Minecraft, will see if it happens again now

[LivacoNew]

Replicated & caught it, you were right, looks like it was this outdated way of disabling middle click paste from older Hyprlands;

I noticed while Hyprland was freaking out it was at consistent small 0.1% CPU, killing wl-paste caused Hyprland to calm back down.

No idea why it would spam clipboard stuff like that, but alas it seems to have been the issue. Will close and use the new variable for it, sorry for wasting your time :)
