Lag issues during GTK file operations

[Striffly]

Description

I've been experiencing significant lag when using the Gnome Sweet theme, particularly when performing file operations in Chrome. The issue becomes apparent when I try to save a file using the GTK file picker modal, or try to navigate through directories with the same modal. The modal takes an unusually long time to appear, and there are noticeable delays when navigating between folders.

This occur even with Gnome extensions disabled
This does not occur with other themes, like Otis

Steps to Reproduce

• Install and apply the Gnome Sweet theme on a Gnome desktop environment.
• Open Chrome and attempt to download any file.
• When the save file dialog appears (GTK modal), observe the time it takes for the modal to show up.
• Try navigating through different directories within the save file dialog.

Expected Behavior

• The GTK modal should appear almost instantly when invoked.
• Navigating through directories should be smooth and without any noticeable lag.

Actual Behavior

• There is a significant delay before the GTK modal appears.
• Navigating between directories is slow, with noticeable pauses between each folder change.

System Information

OS: Arch Linux
Gnome Version: 46.2

Hi, Is this issue still happening? I ask you this because I'm not able to reproduce such behaviour(delay while opening modal dialog)
