Description

When selecting which symbol to add in KiCAD eeschema (KiCAD 8.0.3), RAM/VRAM usage of Hyprland rapidly rises and doesn't drop. Each time you select a new symbol, RAM usage of Hyprland rises for about 10 MB.

After fully closing KiCAD, memory usage drops to normal level.

It's also reported that KiCAD 8.0.3 have a possible memory leakage issue, but when I was reproducing this issue, memory usage of KiCAD didn't rise.

How to reproduce

• Open KiCAD Schematic Editor (eescheme)
• Press A or click "Add Symbol" button. A window should pop up.
• Randomly click items on the left side repeatedly, memory usage of Hyprland rises and won't drop.
• Close KiCAD, memory usage returns to normal.

I tried reproducing this problem on sway and older versions of Hyprland. This issue can not be reproduced on sway and Hyprland v0.39.1. Trying to bisect now.

I assume kicad is xwayland? in that case dup of #6584

I'm running KiCAD (8.0.3) natively on Wayland.

When running with GDK_BACKEND=x11, this bug won't reproduce. So it should be a issue related to Hyprland implementations.

I also noticed that the bigger (more pixels) the symbol preview is, the more memory it takes. Since Hyprland can still free up these memory, probably Hyprland is stocking up image buffer or something related to that but will not use them after generating them / free up the memory when they are no longer needed.

is it ram or vram? If VRAM, are you sure it's not just lazy freeing by the driver?

Both RAM and VRAM. But it seems that the RAM usage increase is more severe than VRAM.

VRAM usage won't drop either, so I don't think the driver is lazy freeing.

This is a KiCAD issue (and shm leak)

Sway itself doesn't leak likely because IIRC sway does lazy alloc but it's definitely KiCad and it does the same (leaky) behavior on sway and hyprland:

[2809502.700] {Default Queue}  -> wl_shm#7.create_pool(new id wl_shm_pool#125, fd 21, 2393600)
[2809502.704] {Default Queue}  -> wl_shm_pool#125.create_buffer(new id wl_buffer#126, 0, 880, 680, 3520, 0)

This buffer created is never referenced again (and neither is the pool) and KiCAD keeps creating them, thus having Hyprland allocate memory for it, thus increasing the VmRSS.

With sway, the leak is still there, but it will likely show up only on KiCAD's memory usage because it's only shared mem.
