I just updated to Construct 2 R229, at first glance I liked the new design of the update until I went to the event sheet and clicked add action, it lags and after I select an object in the dialog it shows the error with a title of "CHECK FAILURE" and C2 crashes. And the error dialog sometimes shows a message about a memory leak. I can't use Construct 2 anymore without crashing.
I also noticed that it only happens on big projects (with hundred of objects) but not on templates. I also tried different types of Icon Mode and still no good. I also get a sluggish performance depending on the number of object in my project.
I'll post a before & after video after I am finished.
Might be helpful:
I am using an ultrabook Acer Aspire Switch 12 Windows 8.1 64-bit.
