memory leaking

[xcccdjsn]

I have used swaylock, hyprlock and gtklock, but all of them will increment memory amount every time after using it.

System Information

• niri version: niri 0.1.9 (unknown commit)

• Distro: Arch Linux x86_64

• GPU: Intel UHD Graphics G4 @ 1.25 GHz [Integrated]

• CPU: 11th Gen Intel(R) Core(TM) i3-1115G4 (4) @ 4.10 GHz

Could it be some mesa GPU objects that will get garbage collected later?

I guess we need to check with the Tracy memory profiler or something to see if there are any leaks on the Rust side.

I added Tracy profiling. I can see the Rust memory increase every time I run swaylock. It's a bit hard to tell what gets leaked. Seems like some surface data might have a ref cycle?

Found it: Smithay/smithay#1573

I have not test other window manager.

I found other application also can cause memory leaking, especially kitty. Spawn multiple kitty in short time, and then close them quickly. I did it many times resulting in lot of memory leaking.

This is my result screenshots.
I also got memory usage from btop which derived same result.

That is exactly what I've been rambling about in matrix room a few weeks ago. Recommend looking at my smithay issue and other linked issues.

Screen locker leak should be fixed with 600cffb

@xcccdjsn could you please test cosmic-comp for your kitty issue? I believe it's not niri specific and there's already a Smithay issue open.

Gonna close this assuming it's the Smithay issue.
