Weird Lag when dragging floating windows

[System-x64]

on setting misc{animate_manual_resizes} to true, the window gets a weird lag or idk what to call it

Is their anyway we could fix it cuz i really love animated resize but i hate this lag thing

[vaxerski]

verify that fact with hyprctl version

[NextWork123]

@vaxerski done. i think we compiled on that commit #51ce3dd

[vaxerski]

huh. Can anyone else confirm it's still an issue?

[GrabbenD]

fixed with 64f35c0

Most impressive that you managed to find this edge case, well done :)

huh. Can anyone else confirm it's still an issue?

I tried your fix https://github.com/hyprwm/Hyprland/commit/64f35c0e3190f3b56a1c17e81c775966bd0a2251 and I removed debug:damage_tracking from my config. Here's my observations:

• It didn't resolve the original issue.
• If I now disable misc:animate_mouse_windowdragging it feels even smoother than before so that's a win.

With OBS and wlrobs plugin I'm able to actually record this issue! Here's a demo (all stuttering/choppiness in the video is what's actually happening on the screen):

Can you (without the damage_tracking opt changed now, you can remove it) turn on debug:damage_blink (warning: epilepsy) and see whether if you move the window quickly the pink highlight follows it correctly?

I jumped a few commits forward to https://github.com/hyprwm/Hyprland/commit/fe007fd36a050103c7953bf5ba68d6ba7187b6e1 and enabled debug:damage_blink (while debug:damage_tracking is still removed). Had to keep it super short due to file size limit. Also, for some reason the damage_blink disappears towards the end of the video, this is a bug in OBS:

Here's my config file, it's mostly default for testing purposes:

placebo, didnt have anything to do with this

It didn't resolve the original issue.

reeee it did for me and now I can't repro againnnnn

your exact config.

:woe:

[vaxerski]

Curves are perfectly fine now (1200 samples)

can't see what's going wrong.

My eyes are playing tricks on me after playing around with this for too long 😅

I tried various monitor configurations to see if that could be the issue but nope (also, just one monitor is plugged in to DP-3 while trying this):

1. 10 bit + default scaling (0x0,1) with:

   • 3840x1600@119.982002 (hyprctl monitors recommendation)
   • 3840x1600@119
   • 3840x1600@120

2. default scaling (0x0,1) with:

   • 3840x1600@119.982002
   • 3840x1600@119
   • 3840x1600@120

3. I also tried a different 8bit monitor. Default scaling (0x0,1):

   • 1920x1080@60

Let us know if there's anything that we can try!

[GrabbenD]

Also confirmed that this doesn't fix the issue either:

misc {
    vfr = 0
}

wat

I tried various monitor configurations to see if that could be the issue but nope

turn on the debug overlay and check the var on animation ticking - if it's not higher than your avg frametime, it should be fine.

curves we know are fine

you say DT on monitor solves the issue partially - frame scheduling is off? but then vfr should fix that

that leaves damage tracking to be the culprit, but if that was the case we'd see "tearing"-ish artifacts and furthermore that should then affect more than just resizing manually but all animations. Besides, it should be reproducible.

wtf.

patch.txt

@GrabbenD try this patch.

edit: oopsie, this: patch.txt

[Estebiu]

It seems to be gone. The animations still aren't as smooth as they could be, tho.

[vaxerski]

Nice. I accidentally committed that patch yesterday. Can anyone else test if the stuttering still persists? If like 3 people say it's fixed I'll close.

[NextWork123]

i can confirm, is fixed thanks.
