Summary 06668: mhavoc, mhavoc2, mhavocp, mhavocrv: Some graphics disappear or are not drawn at all
Description Certain graphics such as enemy ships in the first level will briefly disappear then reappear. Sometimes this can last longer than other times. The "maze" levels (not the on-foot levels) are basically unplayable as a substantial amount of the graphics are not visible most of the time. See attached picture comparing that level in 0.171 to 0.188. The issue started occurring between 0.171 and 0.177.
Steps To Reproduce Start a game and pay attention to the enemy ships. You will see them often disappear for a moment. Get to the maze level shown in the attached picture and most of the graphics will not appear most of the time (see photo).
Additional Information I did not test any of the other versions, only mhavoc (rev 3).

Pretty sure it has to do with the new way vector graphics are rendered by default.
This game in particular doesn't seem to like it and I noticed many bits disappearing entirely even before the maze section you have detailed.

The regression version is 0.174 for mhavoc, mhavoc2, mhavocp and mhavocrv.
For alphaone and alphaonea, they already had this problem since the 0.111u1 - 0.112 cycle (not sure which exact version, I don't have them to test). But in 0.174 they got worse - in the space battle section, nothing is drawn except your ship and the enemy base. The base reactor section seems OK.

Finally found the 0.111 betas, needed to complete my tests in the previous note.
Alphaone and alphaonea have this bug since 0.111u5, that's their exact regression. I hope this can be useful.
