Slight graphical corruption of icons when scrolling in Wood theme

[Soto-Jnthan]

Flashcard or Exploits? Running from SD-Card Base Console: N3DSLL 11.17.0-50E

TWiLight Menu++ Version: Release v27.15.0 TWiLight Menu++ UI: Wood + Default

Expected behavior

Icons should remain fairly consistent while browsing in all theme

Actual behavior

Icons appear with graphical artifacts when scrolling using the Wood theme

Steps to reproduce

1. Run TWiLight Menu++ on a N3DSLL console
2. Set Wood as the theme to be used and disable logging if it is enabled
3. Exit the application while the SD root directory is the active directory
4. Relaunch the application with root directory as the entry point
5. Hold either D-Pad down or up for scrolling at full speed
6. Notice the frequent graphical artifacts on the selected icons

Notes

The issue occurs with both directory and file icons and it is harder to reproduce when logging is enabled.

I was also able to reproduce a few fatal crashes that occur when scrolling after switching a theme, but I will report it once I find reliable repro steps.
