High CPU usage

[turutupa]

I really haven't identified the cause, but if I run picom by itself my PC will run fine. But the minute I run xborders with it, it starts running burning hot. I have shadows and rounded corners applied in my picom config.

I know this is not enough info to learn why its behaving like that, but perhaps you might have some pointers?

Can you confirm it's xborders is causing this? In a process viewer can you report xborders' CPU and memory usage. Also let me know what your computer's specs are

This is my laptop: https://www.amazon.com/ASUS-Entertainment-5900HS-2560x1440-Fingerprint/dp/B097DDZ2MV Specs summary: CPU AMD Ryzen 9 5900HS 8-Core RAM 32GB RAM SSD 1TB SSD GPU Nvidia RTX 3080 Max-Q

As per usage, in htop doesn't seem to show high numbers, around 0.7~1.2 CPU% and 0.2 MEM%.

I do see a change in picom numbers, going from 0 CPU% and 0.3 MEM% to 2.6 ~ 3.3 CPU% and MEM% stays the same.

I know this is still little information... could it be GPU related?

600 MB of memory usage seems high. Does the memory keep increasing is it stable, or in other words is it a memory leak. As for your specs, they seem really good and you shouldn't be experiencing any lag. You can also check your GPU usage by installing a terminal utility for Nvdia cards called 'nvtop.'

Switched to Integrated mode on laptop (disabled GPU completely) and numbers look the same for now, but I think it might not be getting as hot. I see picom get up to 6 CPU% tho, which seems high.

Edit: seems to stabilize around 4.5 CPU%

After running xborders for a while, in sensors I see high temps 74C ~ 79C and high fan RPMs, 3200 CPU RPM and 3400 GPU RPM (meaning GPU was not disabled properly after all) and after stopping xborders I get temps down to 61C and 2400 CPU RPM and 2500 GPU RPM

This is weird, it could be a bug in a library we're using. Will investigate further.
