poor performance while using workspace on headless output

[heisenshark]

I wanted to create a headless display for gaming with sunshine and figured that on my computer the headless setup causes gpu spikes when using headless output, I don't think the usage should increase by +100% so I am reporting this. Even on config that is very close to default it happens. The spikes happen mostly on firefox but they are also present in games. I also tried it on my laptop and cpu/gpu usage increased by fair bit there too.

can you check the debug:overlay? Maybe the headless output has no fps limit and gpu goes brrr

[heisenshark]

when I tested again it really has no limit, the fps value ranges from 1 to 6000

wait, it's Virtual-1, how did you create it? the proper way is to use hyprctl output create headless which should name displays HEADLESS-x

[heisenshark]

I created it by hyprctl output create headless Virtual-1.
After adding monitor=Virtual-1,1920x1080@60,6000x0,1.0 to the config the overlay shows fps number instead of -2147483644 FPS.
Number is uncapped and cant be capped/configured

The issue is 100% related to the latest comments on #5415:

• the numbers of headless monitors keep going up when removed and added(it creates HEADLESS-[23456] etc.)
• the default mode for headless not configured output is [email protected](the only available mode)

May I ask if you can reproduce the issue?

[vaxerski]

it would appear so. I'm pretty sure this is an aquamarine bug though as AQ should handle frame scheduling
