Screen artifacts when moving control points

[Kurt Hillig]

Ghosts of the "local view" box are seen as it is moved while adding/moving control points in the Control Points window (expert mode) - for example see attached or:

This is new and consistent behavior with Hugin 2019.0 on OSX 10.11.6, I didn't see this with any 2017.x or 2018.x versions.

I can't reproduce the artefacts on Windows and Linux. Is this maybe Mac specific? If so can another Mac user reproduce it?

[Kurt Hillig (kwhillig)]

I've verified this behavior on both my desktop Mac Pro and my MacBook Pro
(both running OSX 10.11.6).
Haven't tried it on my wife's new iMac (OSX 12.something) yet, I'll report
on that when I get a chance.

I'm using Niklas Mischkulnig's builds for OSX. I haven't tried building my
own version from the original source, and not sure I'd be successful if I
did try - this is quite a bit more complex than anything I've worked on
before, and my major fluency is in FORTRAN and Perl. But if someone can
direct me to where in the code to start looking, I'd be willing to see what
I can do with it...

This also happens here: OSX 10.11 / Hugin 2019 (including rc1)
Hugin 2018.x doesn't show the problem.

Happens on macOS 10.13 as well.
Not when moving some existing control point but only when clicking to create a new one (which causes the view to zoom in) and then clicking and dragging.

[Kurt Hillig (kwhillig)]

Interesting, very interesting! I haven't tried building Hugin from source
- at least not yet, since you've been very kindly providing this service! -
but I'm tempted to brush the dust off my keyboards (I started writing code
in 1966, and retired in 2015) and see if I can track down this bug...

Could you perhaps share with me the workflow you use when you build a new
version? I've worked on a lot of different systems, but never had to build
anything other than simple Perl scripts on a Mac. So I know about tools
like XCode, but haven't ever used them...

(All of this is explained here as well: http://hg.code.sf.net/p/hugin/hugin/file/6328c520cfef/mac/configure-bundle.sh)

I don't like Xcode either, my first contribution was to move Mac building from Xcode to Cmake.

1. Create the folders (e.g. "development" is arbitrary):
# development
# |- hugin (the source folder, the extracted tarball or cloned hg repo)
# - build

2. (Edit the variables at the top of development/hugin/mac/ExternalPrograms/scripts/SetEnv.sh)
3. cd into development/hugin/mac/ExternalPrograms/scripts/ and run:
# ./download-all.sh
# ./build-all.sh
(this will take quite a while)

4. (You might need to modify hugin/mac/configure-bundle.sh as well)
5. cd into development/build, run
# ../hugin/mac/cmake-bundle.sh
# make

Hugin.app will be at build/src/hugin1/Hugin.app
