Public bug reported: Description: Ubuntu Bionic Beaver (development branch) Release: 18.04 Package: libopencv-imgproc3.2:amd64 3.2.0+dfsg-4build2
The OpenCV version frozen in Ubuntu 18.04 has nasty bug where uninitialized variables in the guts of drawing of a convex polygon runs the output (random horizontal lines), see attached image. This thing can ruin sofware perfecly working on OpenCV-2.4 for people coming from Xenial to Bionic. See attached image to compare properly rendered output and corrupted one. This issue has already been fixed in the upstream (https://github.com/opencv/opencv/commit/fa36b9d3455d62e98554a996dea3ebf7201109c2). It would be worth to integrate the above mentioned patch it the 3.2.0 package in Bionic. ** Affects: apt (Ubuntu) Importance: Undecided Status: New ** Tags: opencv ** Attachment added: "Drawing result comparision.
