headerCanvas, headerViewPort Memory Leak #3889

Open thachp opened 9 years ago

thachp commented 9 years ago

I am running into a huge memory leak problem, where memory usage increase by 50m+ every time I switch between tabs in a single page application.

Grids are dynamically generated depending on the configuration of tab objects pulled asynchronously from a restful service. Each tab can contain up to four grids.

I followed the "three snapshot" technique and narrowed the problem down to thousands of RED nodes under headerCanvas and headerViewPort objects under containerCtrl.

ENV

AngularJS v1.3.16
UI-Grid 3.0.0-rc.21
Memory leak confirmed on IE11, Firefox, and Chrome

I have tried upgrading to RC 22 and upgraded Angular to 1.3.16. The problem still persist.

What are you using to make the tabs? I'm trying to reproduce this locally and haven't been able to so far. Can you reproduce the same issue in a simple plunker with two grids each in UI-Bootstrap tabs? (That's basically what I'm trying).
