O_o Look at that animation. In that animation, look at the south part of the grid. Notice how each time the heighth of the window is decrease what it does to the south part of the grid. Don't you see the grid disappearing? Anyway, I shouldn't attempt to assume anymore, as I could easily be wrong. The image isn't anywhere near small enough to not see the grid draw distance problem. As for v1.2.66 fixing it: Nope. Look and learn. http://www.hlrse.net/Qwerty/anim_dcme_bug2.gif In this one, each frame I am increasing the width of the DCME window. Look what happens to the grid each time I do that. ;o To do the following bug you have to select a few tiles, like the little room you see in the animation. I move it somewhere, then I use middle click to move the view around. After doing that, I just move the selected tiles around. http://www.hlrse.net/Qwerty/anim_dcme_bug3.gif This animation I have to move my select atleast 1 tile, then I can use my middle click (clicking my scroll wheel) and on the radar it'll move the drawn object at a diagonal offset each time I click it. Look carefully at the radar. http://www.hlrse.net/Qwerty/anim_dcme_bug4.gif This screenshot also illustrates something, infact another thing also came to my attention. First I will begin with the usual - look at the radar. The red square shows where my camera is. You obviously don't see anything passing through this selected room behind it. This is again performed with the last bug (above this paragraph; previous animation). http://www.hlrse.net/Qwerty/dcme_middleclick_bug.gif The other thing that came to my attention - the Wall tiles. I have the eraser selected as my secondary, and one of the walltiles as my primary - I have a base or room made from a walltileset... If I delete part of the wall, it won't automatically fix/adjust those tiles properly. When I flip or rotate an object that was made with walltiles, it doesn't fix itself either, like the previous screenshot given shows.
