--- Comment #3 from Olivier F. R. Dierick o.dierick@piezo-forte.be --- Hello,
Thank you for the information.
This sounds like a queue/buffer not processing events in a timely manner.
I think it relates to bug 54858.
I'll check the Steam demo too and if I can reproduce the error, I'll try to implement a Windows.System.DispacherQueue stub function and see if that fixes the issue.
Regards.
