I can also confirm this is still happening with Thunderbird 60.3.0 in Linux; 18 entries in the previous conversations list on a 1920x1080 resolution are triggering the flickering for me. The bug is quite easy to reproduce artificially: * Restart Thunderbird * Connect to any IRC server, e.g. the Mozilla IRC server * Join a previously unused channel, e.g. "#test1337042" * Type something, e.g. "test" * In a console, change into ~/.thunderbird/xxxxxxxx.default/logs/irc/test1337042@irc.mozilla.org/#test1337042.chat (change the path accordingly) * Multiply the log file, use e.g. `for i in {01..12}; do cp <filename>.json 2000-$i-00.000000+0100.json; done` to create 11 entries; repeat for 2001 until the number of entries in the conversations list is just the height of the pane on your setup.
