But my guess is that it is related to\nchanging buffers, like an unfinished writing to a buffer over its\nprevious contents. There is an occasional horizontal \"line\" near the\nbottom of the image, regardless of the camera orientation. With a\nstatic scene, there is no such (clearly visible) problem. But with a\nmoving scene, it looks to me like different images overlap and then\nthere is a visible disruption at the place where one image finishes and\nthe other one starts:\n\n +--------------+\n | |\n | |\n | |\n | ----- |\n +--------------+\n\nIs there anything I can try in the code to confirm the source of the\nproblem?","headers":{"Return-Path":"","X-Original-To":"parsemail@patchwork.libcamera.org","Delivered-To":"parsemail@patchwork.libcamera.org","Received":["from lancelot.ideasonboard.com (lancelot.ideasonboard.com\n\t[92.243.16.209])\n\tby patchwork.libcamera.org (Postfix) with ESMTPS id D6ADFBD87C\n\tfor ;\n\tWed, 27 Aug 2025 09:40:22 +0000 (UTC)","from lancelot.ideasonboard.com (localhost [IPv6:::1])\n\tby lancelot.ideasonboard.com (Postfix) with ESMTP id 8E0BD692EE;\n\tWed, 27 Aug 2025 11:40:21 +0200 (CEST)","from us-smtp-delivery-124.mimecast.com\n\t(us-smtp-delivery-124.mimecast.com [170.10.129.124])\n\tby lancelot.ideasonboard.com (Postfix) with ESMTPS id 787E7613C0\n\tfor ;\n\tWed, 27 Aug 2025 11:40:19 +0200 (CEST)","from mail-wm1-f69.google.com (mail-wm1-f69.google.com\n\t[209.85.128.69]) by relay.mimecast.com with ESMTP with STARTTLS\n\t(version=TLSv1.3, cipher=TLS_AES_256_GCM_SHA384) id\n\tus-mta-517-vNbpawOvPYa46wYFJ-aX7w-1; Wed, 27 Aug 2025 05:40:15 -0400","by mail-wm1-f69.google.com with SMTP id\n\t5b1f17b1804b1-45a1b0c5366so39514235e9.3\n\tfor ;\n\tWed, 27 Aug 2025 02:40:15 -0700 (PDT)","from mzamazal-thinkpadp1gen7.tpbc.csb\n\t(ip-77-48-47-2.net.vodafone.cz.
