I havefound a way to make TDM eating all CPU using grids. Turn on grid on Zoom Level10.
-
Make some small logical model, about 10 entities with attributes.
-
Usually such entities will be displayed in 4 rectangle pages.
-
Turn on “Show Grid” option
-
Set to Zoom Level 46 - about two pages can be seen two pages (and whole model is about 4 pages), so zoom out again
-
TDM switches Zoom Level to 26. And everything is OK, but…
-
… if you click Zoom Out ONCE MORE, TDM will switch to Zoom Level 10…
… and you will end up with idle TDM eating 50% of Dual Core CPU…
It is not technically a bug, but since it seemsthat every window activation turns grid size calculation, TDM ends up trying todecide how to display grid on Zoom Level 10. So I suggest not to display gridfor Zoom Levels lesser than, say, 20.
All of this can be seen on default setting ofgrid size (did not have time to do more experiments).
