'''Affects:''' Windows 7+ (earlier versions may be affected too)

'''Description:''' When trying to exit, the game may glitch up and crash. The cause of this is ~~unknown~~, ~~but~~ is ~~presumably a change in one~~ of ~~the~~ Windows~~/DirectX APIs that LEGO Island uses~~.

'''Description:''' When trying to exit, the game may glitch up and crash. The cause of this is due to [[ISLE.EXE]] not initiallizing a variable before sending it to [[LEGO1.DLL]], although it is still unknown why older versions of Windows are not affected.

Line 47:

'''Affects:''' Most recent versions of Windows

'''Description:''' LEGO Island was written around a very old version of DirectDraw, including a [[Direct3D Retained Mode|retained mode API]] (D3DRM) that is not only unsupported now, it's also been dropped from Windows/DirectX entirely. Many of its DirectDraw function calls are obsolete, deprecated and/or completely abandoned now.

Many of its DirectDraw function calls are obsolete, deprecated and/or completely abandoned now. There is one specific case, on some XP computers (around the time of Vista-compatible stickers) AUTORUN.EXE, and ISLE.EXE are shown as non-compatible Win32 applications, and will refuse to run (has not been tested with Rebuilder, that might fix it).

'''Description:''' When using "Ramp Emulation" mode, all 3D textures are heavily glitched. Bitmaps remain normal:

<center>[[File:Windows_10_1809_Ramp_Bug.png|alt=Inside the Information Center. The Infomaniac is centered on the screen and is showing glitched textures. His arms and face are notably distorted and appears as a noisy, static-like texture consisting mostly of yellow, green and black pixels. His legs and hands appear as gray, along with his hat which is momentarily being tossed above him. His shirt only appears discolored, being more yellow than usual. The two flowers sitting on the red railing are also distorted in the same way. The Information Center's background remains normal.]]</center>

This is a DirectX incompatibility introduced in Windows 10 1809. The exact cause is unclear.
