"Basic" layer rendering is slightly broken.

[LittlePlanetCD]

Before opening this issue, I ensure that...

• I have read the FAQ and confirmed my issue is not mentioned in it.
• I have checked both open and closed issues and confirmed this bug has not already been reported.
• I am not asking for tech support (e.g. game closing on startup, error when trying to build, etc).
• I am not asking for modding support or reporting a bug in a specific mod; this bug either occurs without mods enabled or is directly related to the mod loader.
• This bug is not related to any unofficial fork/port of the decompilation, and any issues with those should be kept in the appropriate repository.

Expected Behavior

Basic layers render correctly.

Actual Behavior

some corners (bottom left and right specifically) tend to break

Steps to Reproduce

1. Open mania, load Press Garden act 1
2. use debug to move while the basic layer backgrounds are active and on screen
3. watch the bottom left.
