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