Daniel et al,
I wanted to provide an update based on the latest official mutter
release as of today - 25.Mai.
The issue still exists. However, I provide the following in the event
it helps to refine the underlying issue. Please let me know if there
are logs that would be helpful to you or
Will do. Thanks Daniel
