[Qgis-user] QGIS 3.4.0 on Mac OS X - separate windows can't be resized

[Garth Fletcher]

QGIS 3.4.0 under Mac OS X 10.12.6

Separate windows, i.e., "Panels" such as
  "Processing Toolbox", "Log Messages", "Layers", "Results Viewer", etc.,
cannot be resized by dragging on their lower right corner (LRC) when
they are separate windows (i.e., not part of the main canvas window).

This problem is new with 3.4.

The cursor does not change to a sizing cursor when placed over the LRC.
