So far no more freezes for me since rolling back to f185b1773cc055b2825651525551593bb86853e7. I was able to reproduce this fairly reliably by scrolling up a ton to view a chat's backlog, and then scrolling down. Doing that, I was able to git bisect and find the culprit: fb3b1490a9803392f7ba1318b89ea33ff73e5d61 is the first bad commit commit fb3b1490a9803392f7ba1318b89ea33ff73e5d61 Author: James Graham <james.h.graham@protonmail.com> Date: Sun Jan 28 17:13:23 2024 +0000 Compact Mode Improvements Get rid of the anchors and move to layouts for th bubble and avatars. This allows the timestamp to be fixed in compact mode so it always sits on the far right. It's also just now more compact than before.  src/qml/Bubble.qml | 1 + src/qml/MessageDelegate.qml | 130 ++++++++++++++++++------------------------- src/qml/TimelineDelegate.qml | 2 +- 3 files changed, 57 insertions(+), 76 deletions(-) Indeed, reverting that commit locally has fixed the issue for me.

Everything from git master with Plasma 6 Wayland on top of Fedora 39. This has happened three times today: when I scroll in the message view, the app will simply freeze forever until force-quit.
