Form is empty if AllowOuterEffects is disabled in skinmanager and DrawNonClientArea is disabled in SkinProvider. It seems this settings blocking or killing the message queue. If you resize the form the form is repainted one time, nothing more.
If you enable AllowOuterEffects or DrawNonClientArea the form is repainted correctly and the time is progressing in the upper panel.
Attached you'll find a simple sample project (Delphi XE6).
