I am running Hyprland window manager and I have been experiencing a problem when I right click a file or folder in KDE Dolphin file manager to open the context menu. When I move the mouse between the options a single CPU core spikes up to 100% usage and the context menu looks like it lags behind the mouse movements and responds sluggishly to input.
There is also this message on the terminal running Dolphin which appears when the problem is happening:
qt.qpa.wayland: Creating a popup with a parent, QWidgetWindow(0x5f47235668e0, name="Dolphin#1Window") which does not match the current topmost grabbing popup, QWidgetWindow(0x5f4723a96ed0, name="DolphinContextMenuClassWindow") With some shell surface protocols, this is not allowed. The wayland QPA plugin is currently handling it by setting the parent to the topmost grabbing popup. Note, however, that this may cause positioning errors and popups closing unxpectedly. Please fix the transient parent of the popup.This is a image showcasing the issue: https://i.ibb.co/9Vd163L/dolphin-bug.png
I have been looking around the internet and the forums and I haven't been able to find anything about this issue. This is also happening with a friend of my running Sway on Void Linux.
This issue seems to have started after the Qt6 update to dolphin.
Has anyone experienced this problem or has any information about it? Any help is appreciated.
EDIT: I am experiencing the same problem with Kdenlive, so the problem is most likely related to Qt6. The same message appears on the terminal running Kdenlive as it does in Dolphin. Altering the title to reflect the update.

I figured out the origin of the issue!
The problem is related to my Qt6 theme.
I have setup Kvantum + qt6ct to select the theme and I used the Dracula theme.
The problem lies on how I downloaded the Dracula theme: I used a zip and extracted it to ~/.config/Kvantum (manual install method).
This causes the theme to not get updated over time and this lead to my issue related to Qt6 as the theme was made with Qt5 in mind as I had downloaded it a long time ago (more than a year for sure).
The way I fixed the issue was by removing the manually installed themes from `~/.config/Kvantum` and installing the AUR package kvantum-theme-dracula-git. After that, I launched Kvantum Manager and changed the theme back to Dracula.
