[quote="clalancette, post:2, topic:5207"] There is clearly something else going on. [/quote] Yeah, as @roehling found out, the issue is the `cv::startWindowThread`. Hopefully, this issue is resolved in the next sync. And no need for bundling OpenCV for such a trivial issue. However, if `cv::startWindowThread` is used in other parts of ROS, it might be beneficial to switch away from that for the foreseeable future. --- [Visit Topic](https://discourse.ros.org/t/ros1-opencv/5207/3) or reply to this email to respond.
