Running Stronghold 2 Steam Edition via Crossover on a late 2013 MacBook Air (Intel HD 5000) and having these weird graphic glitches.
Basically I get what appear to be weird triangles (most just super narrow, others as wide as the main one in the screenshot) from various entities pointing mostly towards other entities (rabbits, workers, ...).
The triangles appear/disappear by changing the perspective (moving the camera, zooming in/out, switching to architect view) and or if the entities move around.
See example Screenshot (red text was a bad choice..) : https://imgur.com/a/LM1enpG
I tried installing it both in the suggest XP bottle and win7.
