Thanks Wayne. I think the confusing part in this ticket is that there
must have been multiple regressions in terms of CPU over time and I
think we are also mixing X and Wayland (in case that matters). Certainly
I also saw a big slowdown between TB 91 and 102.
In any case, with regards to my
I just re-installed TB 115.6.0 from scratch on a completely new Laptop
(Lenovo Carbon X1 Gen 11) running Ubuntu 22.04 and I see exactly the
same behavior there as on my old laptop. I will have to revert to TB 91
as any newer version is essentially unusable for me.

Here is a more recent profile with TB 120b5 in case it helps. As before,
the profile was taken while moving the mouse cursor vertically across
the message pane (no clicking or any other action):

Title:
[upstream] Very high CPU and slow
I just tried the latest 118.0b4. The lag on the mouse-over effect as
well as the high CPU usage is still reproducible for me. First I thought
the new "cards view" is better, but that's just because fewer messages
are visible in the message pane at a given time. As has been pointed out
before,
In my case, I have no add-ons installed and tested with an clean
profile. Compared to Thunderbird 91 the UI is laggy and uses about a
factor 2 more CPU when hovering over the entries in the message pane.

Tested with a clean profile and TB 115 and I still see the same high CPU
usage as with all previous beta releases. Is there anything we can do to
help move this higher in the priority list of the developers?

Tested with a clean profile and thew new 115b1. Problem is still the
same ("feels" even slightly worse, although I don't have hard
measurements on that).

Still no improvement with latest beta (114b3). I really wonder if this
will ever get addressed. For me, it's a definite blocker and I am still
using 91.8 for that reason. But I don't think I can stay much longer on
such an old version. Will probably have to look for another mail client
after 20
I tried the latest Thunderbird 112 beta 6 and unfortunately the
situation is still the same. I also managed to capture a profile of
simply moving the mouse cursor vertically across the message pane
window. My CPU usage goes up to 25% (on a 4-core CPU) while doing so:
Thanks for the update. I just tried Thunderbird 111 beta 2 "Supernova"
on Ubuntu 22.04 but unfortunately the situation (laggy UI, very high CPU
usage on moving mouse cursor in message pane) is still the same. Let's
hope the next version will improve on that.

I am seeing the exactly same behavior as Adi on Ubuntu 22.04. I manually
upgraded to Thunderbird 102 via the mozilla ppa and I am seeing the same
high CPU usage on mouse hover and delayed animations, which made the UI
almost unusable for me. My first guess was also the WebRender as I had
to
Sure, no problem. Separate bug for 16.04 created:

Title:
I am seeing the exact same problem on a Samsung NP900X3G after the most
recent kernel update for Ubuntu 16.04. It works fine on 4.13.0-41 but
with 4.13.0-43 I am seeing the same horizontal lines as Thomas. Maybe
this helps to find where the problem got introduced.

@Rainer Bielefeld: I observe this problem for both vertical and
horizontal toolbars. Should I submit a new bug report for this or is it
the same issue?

I still see the same problem that I reported in comment #20 with Version
3.6.2.2 (Build ID: da8c1e6). It makes LibreOffice completely unusable on
Ubuntu for me. Please let me know in case you need more information.

I am seeing the same problem with Version 3.6.1.2 (Build ID: e29a214) on
Ubuntu 11.04 (x86). In Impress or Writer, clicking on the little black
dropdown arrow of the Font Color toolbar icon has no effect. No
dropdown menu appears. The same is true for some of the other toolbar
icons I tried (e.g.
