Do you have the OS version and which gome version are you on? This will help me triage what the issue is.

I see the issue @jmlc11 @xAspirus - I am sending the fix shortly

[jmmaranan]

Hello @jmlc11 @xAspirus, would you be able to build from source? And see if this resolves it? https://github.com/jmmaranan/forge/tree/fix-update-decoration-lag.

[xAspirus]

v46 has less lag but it still stalls sometimes. the stalling happens when the stacking hint is drawn.

[harshkhandeparkar]

v49 still has this issue. It's better than before but still laggy.

@harshkhandeparkar - do you have a screen capture of this behavior? I am re-opening this.

Also: GNOME 42.2, Arch Linux, X11
I also have Blur my Shell, Gnome 4x UI Improvements and Just Perfection in case you need this information. (although the issue persists even after turning these extensions off)
Forgot to mention earlier :)

Do you use integrated graphics or dedicated like Nvidia? I see the lag only when there's like 10+ windows - I am on Nvidia Fedora 36

Hi @harshkhandeparkar - I added some more optimizations on the sorting/looping. Would you be able to try the main branch?

I do have dedicated Nvidia graphics and the screen runs at 144fps smoothly except while dragging. This is another screen recording, this time with the panel. It seems that the screen just stops rendering (notice the clock time on the panel) except for the cursor.

I'll try in a few hours and let you know.

It doesn't lag if tiling mode is turned off.

[harshkhandeparkar]

Found some more information. I use a laptop with an external mouse connected. If I drag the window using the mouse, it lags. But if I use the trackpad, it doesn't. Very strange behaviour.

[harshkhandeparkar]

I also tried the master branch and it seems to have improved a lot but still laggy.

I want to add to this. I also use an external keyboard and I tried typing on both keyboards once and it actually created a similar kind of issue. The screen just stops rendering while typing with both keyboards simultaneously. Don't know if this is an issue with wayland as well. I will investigate further and let you know.

[jmmaranan]

Thanks! Can you try to install or enable xorg? Also are you on internal graphics?

I am using xorg and dedicated graphics currently. I tried to use wayland but for some reason the option doesn't even appear in gdm :(

[jmmaranan]

Hi @harshkhandeparkar - I made more optimizations to the main branch. Can you try if it improved a bit on your end?

yes sure!

It is still quite unusable with mouse but dragging with trackpad is very smooth.

I (@xAspirus) am on Version 52, and now I experience no lag. It has improved since. Thank you

[jmmaranan]

@aspizu - thank you - closing this one

[jmlc11]

Yes, thank you!
