Issue after Overscan

Good day!

I am working on the Circuit Sword, and used the Overscan to make it a more ideal fit. Issue is, after the 1st third of the screen (vertical split), the rest of the screen has horizontal distortion, and keeps flashing around. It only happens after it finishes start up, until I then shut it down.

These are the changes I made:

# Enable DPI
dtoverlay=dpi18
overscan_left=10
overscan_right=10
overscan_top=5
overscan_bottom=15
enable_dpi_lcd=1
display_default_lcd=1
dpi_group=2
dpi_mode=87

I went through several different values before I figured out what was ideal, and they all made the same issue. When I change the overscan back to 0, it resolves the issue, but then parts of the screen are hidden again. Any ideas?

Thanks!
