I had several misgivings with Thunderbird v91, the high CPU load being certainly the weightiest amongst them. I don't recall all the issues but just to note one or two others:
Opening additional TB windows (most notably composing a new mail) causes visual artefacts with parts of the window missing. I have to click out and back in to display it properly. FF has also had visual issues when launching in full screen mode for the last several months, maybe it's related. I have Intel 915 graphics.
This is likely due to the setting: media.hardware-video-decoding.enabled true Prior to 91, (with 78) I would get entire windows above FF that were no redrawn (erased) until I placed focus back in the FF window (then the redrawing would occur). That was with the nvidia driver. I currently have the hardware force-enabled turned off, e.g. media.hardware-video-decoding.force-enabled false
Also new items in the Folders / Feeds pane no longer show a preview on hover. A small thing but something I found useful particularly with my feeds. I could get a glimpse of what new feed items I have without the folder losing its blue highlighted 'new content' status.
Have you witnessed either of these under v102?
In 91 I do still get latest message preview on folder hover. I don't recall even testing that on 102. I have my 102 profile saved, I just need to copy it back to ~/.thunderbird under another name and update the profile.ini. I'll check next time I run it. Your not seeing them may be Gtk theme related of all things. I'm not sure, but many apps roll-over-and-die unless you have the gnome default Adwaita theme in use (that's a whole additional issue how Gtk has gone to hell in +3 and 4) The loss of preview could also simply be due to feature removal from Gtk. That will continue until at least 4.14 or so. There are planned breaks of backwards compatibility through that point. If "Gnome" doesn't use a feature anymore, they just chop it from Gtk. That has screwed a number of apps and why gimp still makes use of gtk+2 to a large degree. (rulers were removed in gtk+3) It would be nice to know why the previews no longer work. If you use the default Adwaita bland vanilla theme (even in dark mode), then it is likely a feature removal issue. It may also be work disabling the hardware acceleration use and restarting tbird to see if that may be related. (if I915 is going through a rough patch there) Good news is 102 looks like it actually provides so nice new summary displays to pull everything together on one page. At least it looked like good thought went into it. Better part is tbird still looks like it does now if you don't want the summary page up (that shows sanity in this version jump at least) I'm not sure what the next esr will be, but if it's 102 based, it looks like a good thing.
