Research direction

Start by inspecting CQ-editor's PyQt5 application startup and settings handling, then reproduce the missing-menu and ineffective-scaling behavior on a high-DPI display with QT_SCALE_FACTOR set. Determine whether the existing settings path or environment variable is being ignored; done means useful global scaling works and the menu remains available.

Written by the indexing model from the issue text.

Description

Issue:
Like many QT programs cq-editor fails to scale useful on high dpi screens.
Often used go around is to set the env variable QT_SCALE_FACTOR to a nice value.

Unfortunately doing that CQ-Editor shows no menu and did not use the scaling.

Only the font in the editor could be scaled by settings.

Solution:
Add a global scale preference or make use of the environment.
