Massive lag when calling up the window overview

[Tealk]

Hi

when i have the extension active and call up the window overview, it takes almost a second before there is any reaction at all. If I deactivate the extension, it works immediately.
Neither CPU nor GPU show increased load.

Hi, does this still happen if you disable all other extensions and restart gnome shell?

[Tealk]

Im on Wayland, i cant restart 😅
I only have very few extensions anyway, but even without other extensions it hangs a lot.

Yeah I meant "restart" as in "log out and back in"

Can you please enable debug mode in rounded-window-corners settings and provide the output of journalctl -f -o cat /usr/bin/gnome-shell while opening the overview?

I can tell this is happening, rounded corners is a huge demanding extension, but even on older GNOME versions, on a powerful desktop you may not notice that at all but on a more (performance-wise) restricted environment like a laptop, it does.

Shouldn't an AMD Ryzen 7 7840HS and an AMD Radeon RX 7700S be enough?

It's more about optimization than the hardware resources you have.

If you notice that on a powerful hardware, imagine on mine which is a 6650U with an 660M... 🤦‍♂️

Oh yeah. With a few floating windows I get massive stuttering when going into the overview with rounded corners. With it disabled, it's buttery smooth.

The same happened with me, I think that's one of the reasons why GNOME decided to not implement round corners for all apps, at least, it seems like they rather will search for more elegant solution

Hi, I think I have found what causes the massive lag when calling the overview.
It is the addShadowInOverview workaround.
When I comment out the function call on extensions.ts, line 82, it works smoothly even with a lot of windows open.
