As you rightly say, this issue is not specific of AJE, it is a rare issue that plagues more or less all Ageod games for some users and configurations, and that has never been solved, AFAIK.
I myself get it, very rarely.
My empirical advices are:
- first and foremost make sure you have directx 9.0c. If you have a new windows 10 PC, you may not have directx 9.0c, and the directx 10/11 compatibility with version 9.0c is not perfect. Head to microsoft (https://www.microsoft.com/en-us/download/details.aspx?id=8109
) and install directx 9.0c, it has absolutely zero deleterious effects.
- then in-game there are certain settings that may help: In Options > System, try to turn off display borders and/or decrease memory usage to 25 or 50%. If it does not work, reduce Max Texture Size.
- screen savers running behind the game may also cause problems, try to disable them
