If the player creates a light source next to a chunk boundary where the current chunk X position is greater than the chunk beside it. The player then closes the game, and reopens making the first 3x3 chunks generate lighting is not shown on the boundary chunk.

Expected result:
Lighting crosses the chunk boundary for all forced chunks in the 3x3 grid.

When a chunk is created and there is no chunk created yet for it's neighbors it causes the lighting to make chunk boundaries visible. This has to do with the way surrounding chunk block and lighting maps are passed to the compute_chunk() in main.cpp. Either find a way to make the boundaries disappear without keeping track of missing chunks when a chunk is initially computed, or track the missing ones and after generating a chunk check all surrounding chunks to see if they needed that chunk to properly compute lighting. The screenshot below shows the bug affecting clouds. If you are in the chunk that contains the clouds and make any change to the chunk (placing / removing blocks) the boundaries dissapear since the surrounding chunks exist now.

Currently the GUI elements are created using immediate mode. This should be converted to retained mode at some point to increase performance.
