Gradebook running slow and freezing

Re: Gradebook running slow and freezing

Hi Nicole and others...

We have identified the issue that's causing the delays. Applying the touch-action style to several elements seems to cause Chrome some issues. In the Boost theme, Bootstrap version 4-alpha is being used. In the _reboot.scss file (line 263), touch-action: manipulation is being applied to several elements to prevent the click delay that some browsers don't remove when using meta content="width=device-width".

If you reset the touch-action on these elements (to "auto") within the grade book, the delay is gone.  I believe it's Chrome that is ultimately misbehaving but I don't believe it will be corrected anytime soon.

Attached is the fix we are deploying to resolve the issue in the grade book. I will be making a tracker issue soon.

Hope this helps!

Thank you so much for your reply. 

Can you tell me if you have a link to a modified styles.css?
