Hey Leslie,
what extensions are you using? I just installed gnome-shell-3.26
from Arch Linux's testing repos and it's working fine for me using
btrfs. gnome-shell is hardly visible via 'top'.
Kind regards,
Olaf

Do not (as 5
October) use Gnome with btrfs. You can experience
gnome-shell looping with 99% cpu busy, schemas not being
adhered to, and problems because btrfs uses copy-on-write.
I have 5 copies of Gnome 3.26 with ext4, brtfs fully, btrrs
with xfs for /home and more. I can substantiate the btrfs
problem. Like any scientific experiment, you can duplicate
my findings.
Gnome is safe with a non "copy on write" file system.

Hi
Florian
I'm using a few
of your Gnome extensions. I thank you for
providing them to the community.
I do have a
question for you regarding the gnome-shell.
I have extensions
(several that include yours), where the
installation (doing the settings) onto a
btrfs file system crashes the shell, or
causes the shell to go into a 99.9% cpu loop.
If I install these extensions onto a non btrfs
system, eg, ext4, lvm, xfs , the
installation and extension setup works
flawlessly.
I use most of
your extensions, that come globally with
Fedora Linux (currently using the Fedora beta
1.5, the pending go-live beta). I am using it
fully with btrfs. I can crash the shell with
one or two extensions, only if the underlying
file system is btrfs
As the
gnome-shell gets maintenance updates, I am see
fewer and fewer crashes, but not with btrfs.
The crashes only occur during parameter setup.
It seems that the gnome-shell does not wrongly
read the compiled schema or ignores the
compiled schema. Have you stress tested
Gnome-shell under btrfs?
My preferred
third party extension that works perfectly
with ext4 and xfs is TaskBar by Zpydr. I am
walking through the source code and with my
level of JS knowledge, find no errors. Setting
TaskBar up onto a btrfs
system crashes the shell, but on
logging in after a crash, I see settings
outside of the schema settings. After a few
crashes, when the settings are what I wanted,
every extension works as anticipated. By the
way, I am not the author of this extension.
The author appears to have abandoned his
offering. What is his extension and one or
two others exercising that cause this grief.
I
am wondering if recompiling the schemas while
under btrfs would make a difference. I will
give it a try.

When I started with Gnome 3.24 and then 3.26 , it was a nightmare. I was testing with TaskBar by zpydr.
The angst I had was with TB's configuration under btrfs. Once Taskbar was setup on btrfs, (6 or more tries, with one reboot for each configuration parameter) TB seemed to work unless gnome-shell entered a high cpu loop during login.
That same extension, with the identical gnome 3.24, and then with Gnome 3.26 but using ext4, or xfs, or lvm worked just fine.
To prove it was gnome-shell, I created a /home2 as ext4
and did a sudo cp -ra /home/* /home2
I renamed the two entries, /home to /home2 and /home2 to /home within /etc/fstab and rebooted. The taskbar worked as expected. HOWEVER extensions in the global area /usr/share/...
were tempermenta (btrfs)l. Sometimes the TB or those extensions worked, sometimes not. Reinstalling on the same computer, same disk, same software but without btrfs was and is just fine.
I am using Taskbar with btrfs. Between the time I raised the bug report and today, there have been many many (more than 2 dozen updates) to Gnome. With each update, increased stability.
I allowed the automatic bug reporting software to send almost 40++bug reports about Gnome-shell crashes.
I am testing Gnome 3.26 evolution. It seems that this email I am responding to is 10 days old. Sorry..
