xlet-settings.py performance issue

[ByteEnable]

• Cinnamon 4.8.6
• no daily builds
• Fedora 33
• NVidia GTX1060
• X86_64

Issue
xlet-settings consumes high amount of CPU and heavily sputters and freezes while attempting to scroll through icons in the menu dialog -> icons. After some amount of time the CPU load decreases and the dialog becomes responsive which suggests some sort of caching or list is being created.

Steps to reproduce
Install papirus-dark icon theme.
Right click Menu -> Configure -> icon. The icon dialog pops up and select applications from the left pane. Attempt to scroll through the icons.

Expected behaviour
For the dialog to scroll seamlessly and not consume high amounts of CPU.

A couple of things. First, this is not actually a cinnamon issue. The dialog is actually provided by xapp. Second, and more important, there is really very little that can be done to speed this up from a coding standpoint. Processing that many images requires large amounts of bandwidth from your hdd/ssd/nvme, regardless of how efficient the code is. The only way to really speed it up any more is to use a faster storage device.

Its a running on a Samsung SSD Nvme @ 3500 MBps.

Thanks for the runaround.
