Blackboard Collaborate Ultra

Browser freezes intermittently when sharing application or screen on Windows

The user sharing an application or their screen may experience the Collaborate tab, or entire browser, freeze for 1-2 minutes before becoming responsive again.It has been reported in some instances that the browser crashed or remained frozen indefinitely, requiring a force quit.


One workaround is to try using a different supported browser until a fix is released.

1. Chrome users should disable "Hardware Acceleration" by going to chrome://settings > Advanced > under System turn off "Use hardware acceleration when available" > Relauch Chrome

2. Another possible workaround for moderators who are appsharing presentations is to upload the file to the whiteboard instead, if possible. This is also a best practice for optimizing bandwidth consumption.
