Quite possibly. Look at the Design menu, at the "Automatic Reload
and Preview" option at the top.
I am running OpenSCAD version 2025.05.16.ai25460 (git c76900f9a)
on Ubuntu 22.04.5 LTS.
That box was not checked. Note that previously it was a render that it
did, and not a preview. When I check that box, it will preview as soon
as it loads, which is not nearly as bad, being, in general, shorter
than a render.
I then unchecked that box, and now it still previews when I double-
click the SCAD file, but does not preview when I load OpenSCAD and
drag/drop the same file into OpenSCAD.
I'm testing with a simple cube;
echo ($preview ? "preview" : "render");
cube(10);
In both attached images, 'Automatic Reload and Preview' was NOT
checked, but double-clicking on test1.scad gave me the result in the
attached test1.png
When I loaded OpenSCAD and drag/dropped test1.scad into it, test2.png
was the result.
If I run OpenSCAD and drag/drop a .scad file into it, it doesn't
render
it immediately.
If I double-click on a .scad file, it loads, and immediately starts
rendering. Of course I can't immediately stop it, which is a real
time
waster.
Or is it a bug?
It does seem like a bug if those two cases are handled differently.
(But my experiments have drag-and-drop previewing immediately, just
like double-click-to-open.)
