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. Regards

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.
