Crazy Taxi - CrazyBox window frame glitch

Window frames glitch in Crazy Box (Crazy Taxi) or Crazy Pyramid (Crazy Taxi 2).
This occurs with graphics APIs other than OpenGL(per-pixel) and DX9.

However, this can be avoided for all APIs by setting either of the following:

• Enable Native Depth Interpolation
• Set the internal resolution to 1.5x or more.

Is it due to my GPU or is this expected?

I can reproduce the issue on my GTX 1080 and on Adreno 630 so it's not specific to a GPU.

Partial fix for OpenGL (non per-pixel) on the dev branch.
