Message pane blank after upgrading to 91.2.0
After upgrading to version 91.2.0 Thunderbird no longer shows message content in Message pane. First time after starting Thunderbird I can see that a blue bar is shown (in just a blink) in the Message pane, but no more after that. If a double-click on a message in the list it opens i a new windows but with no content (blank). If I right-click on the message and selects "Open Message in New Windows", it opens in a new window and shows the content. Strange.
I've done all the recommendations to disable all add-ons and clearing the startup cache. However, if I turn Troubleshoot Mode On everything starts to work. The interface even starts to respond much quicker when I click on a message.
I use Gmail (IMAP) and Thunderbird local directory is set to a folder on a network storage (Synology NAS).

If it works in safe/troubleshoot mode, it's probably because hardware acceleration is enabled in normal mode (Preferences/General/Indexing), as it's disabled in safe mode. Disable it, then restart TB and see if it helps. Otherwise, launch in safe mode, 'Reset toolbars & controls', 'Make changes & restart'.
Disabled hardware acceleation and restarted TB in normal mode. Still not working. I choose 'Reset toolbars & controls' and 'Make changes & restart' in normal mode. Still not working.
So therer is something else in normal mode that prevents messages from being viewed in the message pane.
Found the problem. It's the "Thunderbird Conversations" extension that is causing the problem. After disabling it the problem went away in normal mode.
