Switching Icon Caching on or off doesn't seem to make any difference, the lag in both cases is the same. However, not having unique icons in the editor makes development extremely difficult, especially in a big project with hundreds of objects and long object names. Setting "Icon Mode=Don't show unique icons" removes the lag completely. In blank or small project there is almost no lag.
The issue seems to be related to icons and the delay depends on the number of objects in the project.
When running C2 in Windows 10, event dialogs are opening with a significant delay.Īfter restarting Windows 10, the lag disappears, but after several hours/days it becomes more and more noticeable and could reach 4-5 seconds.
