I'm on Leap 15.3. Held off the update from Thunderbird 78esr to 91esr
for quite a long time because I'd read of one or two issues and knew it
might be best to wait a while.
Now, let me state that I've been using Thunderbird since pre-1.0 days
about twenty years ago. It's always been rock solid stable, sometimes a
bit old and clunky but absolutely reliable, more so than just about any
other software I use. I also understand that open source developers
don't get enthused by criticism and they give their free time and energy
and we should all do our best to show appreciation and be constructive
in our conversations and hug trees.
With that said, all current Thunderbird developers must die!
Okay, I'll back off a bit. After twenty years of rock solid stability I
upgraded to 91esr and have run into a catalogue of irritations, some of
which I should have actually catalogued because I've now forgotten for a
moment what they are, but I'm sure they'll come back to haunt me some
more. In the v91 release notes I see lots of happy-clapping for spangly
new features that are of no relevance to me. I just want the continued
Somebody already remarked on here some time ago that scrolling in the TB
message preview pane is now horked. I either have to click or move the
mouse about erratically in the pane to get it to scroll. Sometimes it
scrolls immediately, other times not, and seems worse when there's
images in the mail but no consistency or logic to it. Tried turning on
hardware acceleration and for an hour or so thought that had cured it,
only for the problem to return many times since.
One or two other smaller annoyances I'll just have to put up with for
the time being, but I'd like to know if anybody else has witnessed high
CPU usage, specifically in Thunderbird 91esr on Leap 15.3? I wondered if
it was continually reindexing my twenty years' archive of folders, and
at first it seemed to do it fairly routinely once a day in early
evening. But then it became more frequent, and now it spins up several
times a day. This laptop has been ultra quiet for three years. 8 cores,
32gb of RAM, all of which I barely use. Bought it secondhand-like-new
and it's way overspec'd for the mostly mundane tasks I require of it.
Only very rarely does a CPU intensive task spin up the fan and make any
noise noticeable, briefly. But now Thunderbird is doing this
consistently. At this rate, it's going to wipe two years off the
lifetime of this machine.
I do NOT have the global search and indexer feature enabled. I tried
deselecting and reselecting it as OFF just to make sure. If I look in
Plasma's System Activity when the high load occurs, I see Thunderbird
showing typically between 6 and 22% CPU load whilst most other processes
are rarely pushing more than 1 or 2%. There may be subprocesses amongst
the bazillion other kworker and whatever garbage things further down the
list, but I can't pick out anything for sure. Nothing that nudges more
than a percent or two.
It's also not the Compact Folders process, because I still only do that
manually after a prompt. It just prompted me for the first time in a
long while (I have it set to only act with over ~200mb wasted space),
and after that ran for a few seconds, my system just went into some kind
of hyperdrive like never before witnessed, whilst Baloo reindexed for a
few minutes and half the neighbourhood lost power to the centrale
nucléaire whilst Mr Linux plays with his email client.
And now Firefox has decided to join in the fun and games. Again, the
standard latest ESR version for 15.3. Most particularly when I start
playing anything in YouTube, but not uniquely that. System Activity
usually shows a process 'RDD' consuming one core, and my fan starts
going into warp speed again. Never happened before this last week or
two. In both Thunderbird and Firefox I've turned off all studies, data
collection, error reporting and whatnot to eliminate that.
It could be that others have these symptoms but don't notice on their
desktop fanless or soundproofed machines. What could be the cause?
No I haven't yet filed any bug reports. I'm unsure if it could be
openSUSE-specific, perhaps some other dependency like a graphics update
that has nothing to do with Mozilla. Too many vague things to know where
to even start. And no I haven't tried creating a blank profile because I
can be almost certain nothing will go goofy in such an empty profile,
and I don't want the inconvenience of setting up and receiving pop mail
in a fresh instance and then having to merge it all back into my main
mail at a later date.
