High cpu usage, sometimes GPU usage.

[PauldeKoning]

I am getting relatively very high cpu usage (10-20%) even when the program is idle and not playing music. Furthermore it's sometimes using my dedicated GPU for 5-10% which it shouldn't do in any case I believe.

I have an i5 6600k and a rx vega 56.

I came to post this. I usually run DOTA 2 at around 100FPS on a 120Hz monitor so it's noticeable when I have lower FPS. I had this running in the background and it froze multiple times.

When I turned it off, my FPS probably doubled - not even joking. Extremely heavy on the CPU and possibly memory. Using the browser is much more efficient.

I've seen those issues myself. This shouldn't be an issue in my rewrite. Sorry about the long delay on that.
I suspect I may have a memory leak somewhere obscure.
I expect to be back on this project in the near future.

Hi Martyn, I also experienced this problem recently - even just after loading the app i experienced ~3% gpu usage

Dang, same here.

I love this app, but I've stopped using it for now. I do a lot of animation and compositing, and my computer locks up regularly if I have it open, once I discovered it was the culprit and closed it, no issues.

Note: the same thing happens if I open the official Youtube Music website in chrome, so not sure it's the app that's the issue. But if you have any way of restraining Youtube music that'd be amazing.

Looking forward to this getting fixed.

I suspect it might be something to do with a YouTube music bug. When I installed YouTube music's official PWA (which is nothing more than a standalone chromium tab) I also had this problem. I do not have it when running YouTube music as one of my regular tabs though. So I feel like it's either a YouTube music or chromium bug.

Following on from your point Paul, I don't observe this behaviour when using YTM on firefox

[Hi-Angel]

Since the problem persists on a browser as well, I collected some observations, hopefully they will be useful:

• --no-sandbox fixes it for Chrome
• The problem may happen in both Chrome and Firefox, however on Firefox it happens sporadically, whereas in Chrome it's always reproducible
  • in Firefox the problem may appear at first, but then go away. From what I've seen it never reappeared again unless I restarted Firefox. Closing/Opening the tab in particular never made it start reproducing again for me.
• Problem never appears in Chrome nor Firefox if you are logged out. IOW it is only reproducible when you're logged-in.
• CPU usage is a little bit higher in Chrome (≈22%), than it is in Firefox (≈16)
• In both browsers the process has lots of threads — graphics stuff, audio, media… However, the CPU is always being taken by the main thread whose TID is equal to the PID.
• it's caused by various timeouts
  • Chrome repeatedly calls a futex() and gets a "Connection timed out"
  • Firefox repeatedly calls a poll() on read-side of a pipe, but receives TIMEOUT

[Hi-Angel]

Found a workaround for Chrome: running it with --no-sandbox makes problem disappear.

Couldn't find something similar for Firefox, because I no longer can reproduce it there.
