With a classic Gnome session, this can't be reproduced. Looks like a floating point issue from what I see # Additional info: <!-- The exact package version is compulsory. --> * package version(s): 9.2-2 * config and/or log files: I'll try to attach the coredump info if possible, please see below... * link to upstream bug report, if any: https://tracker.ardour.org/view.php?id=10244 # Steps to reproduce: <!-- Describe how to reproduce the bug step by step including the commands --> 1. start ardour9 2. take over configuration from ardour8 or not, makes no difference 3. start with an empty template 4. coredumps...[ardour9_coredump_20260313.txt](/uploads/b9674fc8e6bc2f309f86d9f025b78fb8/ardour9_coredump_20260313.txt) 5. don't know if I can insert the complete 37.2MB file here, but I'll try...

Coredumps on KDE Plasma as well, so like Robin Gareus from upstream mentioned, it's probably Wayland related... Thanks and cheers, Wolfgang
