Filelight in the background with radeontop displaying noticeable GPU use.

SUMMARY
Filelight appears to be constantly using the GPU when in the directory map view. I could reproduce this both on an Intel Haswell and AMD Raven Ridge system. I also tested this with the version from Debian Bookworm (22.12.3), where I couldn't reproduce this issue. As such, this might be a regression from commit https://invent.kde.org/utilities/filelight/-/commit/e06fcc2e‍.

STEPS TO REPRODUCE
1. Open Filelight
2. Analyze any directory
3. Inspect GPU usage (with intel_gpu_top, radeontop or any sufficient tool)

OBSERVED RESULT
Filelight consistently uses a noticeable amount of GPU resources.

EXPECTED RESULT
Filelight only uses GPU resources right after analyzing is finished or when being interacted with.

SOFTWARE/OS VERSIONS
