Hello everyone,

I’m new to Linux and have been using **Fedora 43 KDE** for about a month.

I made a video to illustrate a problem I’m experiencing in the Start Menu:

In the video, at the beginning, I switch back and forth between two categories in the Start Menu: **Jeux** (Games) and **Multimedias**. This allows you to clearly see the applications in each category, and there’s no issue at this point.

However, in the **Games** menu, where there are many icons, whenever I scroll using the mouse wheel and then click on another menu, such as **Multimedia**, some games or game entries from the **Games** menu often appear in the wrong menu—in this case, in **Multimedia**.

The scrolling action with the mouse wheel seems to trigger this issue.

Steps to reproduce:

- From the Start menu, go to a category with many entries and a scroll bar (Games in my example)
- Scroll through the category's contents.
- Click on Another menu" (Multimedias in my example) : Some entries from the previous menu will replace other entries in the new category.

Fedora 43 - KDE Plasma 6.5.5 - Wayland - Kernel 6.18.6-200.fc43.x86_64

Can't reproduce this on git master, looks like some odd caching issue.
