Description

Hyprland seems to leak memory during any form of screencapture. Specifically RAM, not VRAM. The memory usage of the Hyprland process balloons infinitely. I can also repro this on the default config. The only thing that seems to impact the leak at all is monitor refresh rate: the leak is slower on 60hz and faster on 144hz.

An example of the leak over the course of a few minutes of screencapture in OBS while leaving the system completely idle:

#!/bin/bash
while true; do
    sleep 30
    ps -p $(pidof Hyprland) --no-headers --format "etime %mem vsz rss comm"
done

      11:57  0.9 3675420 301724 Hyprland

Process memory steadily increases. After a few hours, it can reach above a gig. Other than on -git, this is also present on 0.43 and 0.42. Logs do not show anything of interest. Also, this is on AMD.

How to reproduce

1. Start Hyprland
2. Start a screen capture, for example in OBS
3. Observe the memory of the Hyprland process increase continuously

can you bisect this

[cuddleplush]

Didn't bisect yet, but I've found the cause - having VFR disabled. With misc:vfr enabled, the leak is gone as far as I can tell

[Pegoku]

This also happens to me ~when screensharing on discord~, didn't find any cause. Arch, hyprland-git

[Pegoku]

it uses +10GB, sometimes it goes over 13GB

[vaxerski]

great, can you bisect this

[cuddleplush]

can you bisect this

@vaxerski this is the first bad commit ec672b1ab95e341a0dcb6679592ae4e5eea9b1cf

@ikalco regressor moment

@ikalco regressor moment

i remember fixing a similar issue when I wrote it its probably related to the wp or sp of the individual frames not getting deleted

[vaxerski]

you wanna debug it or do I have to do it

[ikalco]

you wanna debug it or do I have to do it

it'll be a few days before i get the time for it so you can if you want to get it done fast

[vaxerski]

I'm working on other things, so no hurries

[cuddleplush]

@vaxerski @ikalco Any update on this? Still present as of 0.44.0

[vaxerski]

I don't have it so debugging might be tricky but ikalco said he can work on it

Thanks! So far looks very promising, after 3 - 4 hours of screencapture I'm not seeing the leak, but I'll test more just in case
