Follow-up Comment #96, bug #49053 (project octave):
@rik Thanks for the thorough review. I can fix most of those issues. Here are
some answers to your other questions:
1) The per-figure __device_pixel_ratio__ property is only updated when the
screenChanged signal is fired. So, I don't think there is a ton of overhead.
2) I don't think the window size problem is due to your version of Linux. I
think this has to do with the fact that Linux and Mac handle window size
during transition between screens of different DPI. I am investigating this
further, but suspect we may need to further distinguish between Mac and
non-Mac HiDPI and on Linux machines whether the screen was created on the
HiDPI or LoDPI screen. There seems to be some window scaling that occurs at
the OS level on Mac, but not on Linux.
I will try a re-work of the patch, and include some debugging output so I can
see why @sschoeps Mac machine isn't behaving the same as mine.
