Hi,


ah, I had assumed something like this, thanks for fixing, Tom! :-)


#actualScreenScaleFactor is a very helpful tool, but I do not yet see the whole idea of the changeset.

In what sense is this meant to be a complement of RealEstateAgent >> #scaleFactor or rather an orthogonal concept?

After loading the changeset and resetting my UI theme, the background image of the world disappeared and all new windows are huge, but they still have a tiny font - am I supposed to set the #scaleFactor manually (to 12, in my example)?

Where exactly can I see any components in the image that are upscaled by the new changeset?

Best,
Christoph

Hi,

turns out, we try drawing things while we load things :)

In the attached, updated changeset I moved the #displayScaled definitions first so that we can happily resume drawing. Also, I removed the usage of the deprecated #anyOpenWindowLikeMe, which caused my image to freeze.

Best,
Tom

That is part of the Change set.
Which class misses that?

Also, one might have to reset all the UI themes.
