Ui freezes on ie 11 with a large number of columns

I am using angular ui grid plugin 3.2.1 and I am using it to render a very column heavy grid( it has around 90 columns). All columns are rendered using cell templates since special conditions need to be handled. Around 20 percent of the 90 columns are dropdowns with 200-300 items each.

I am also using the angular spinner to show a loading bar on each http service call.

My problem is this.

The spinner freezes after the service call returns because the UI grid is struggling to render around 50 rows of 90 columns each. After some time the user gets the infamous slow loading script error message from IE 11. This also happens if the user clicks inside the screen when the spinner is frozen.

Can you please look into this asap?
