Recently updated to GreenHopper 5.8.3. The version upgraded from is 5.4.2. Also could reproduce on GreenHopper 5.7
Chrome version: 15.0.874.121 . Reproducible on Windows/Linux/Mac.
When Browser is zoomed in (Apple + Plus key), scrolling, paging up/down becomes very slow. When I reset the zoom to 100%, problem goes away. Switching to Card View or Summary view also makes the issue go away.
This does not occur on FireFox/Safari.
It seems related to http://code.google.com/p/chromium/issues/detail?id=67558 but not 100% sure. This wasn't happening on this same Chrome version in the previous GH version I tested (5.4.2). Could just be a Chrome bug at play here but would be ideal if there are workarounds as I don't have much faith in the Chrome bug being fixed anytime soon--it was filed last year.
To Reproduce:
1. Go to planning board with about 200 issues per page or so.
2. Change to List View
3. Customize the List View to populate it with a few two or three more fields than the default. You can add Components and Versions.
4. Zoom in to 120% on Chrome
5. Scroll up and down the list...slowness ensues on the browser side.
