Please be careful to only discuss one problem per bug report. If you're experiencing multiple problems then please open separate bugs for them.
Continuing with this bug... I suspect the problem here is that disk IO is directly affecting animations. They shouldn't normally be related to each other, but one way that can happen is if gnome-shell is blocked in writing a log message. It can become blocked if there are regular log messages being written, and then every 5 seconds the kernel will block in order to flush to disk. Please run this command in a Terminal window: journalctl -f Now reproduce the problem again and please tell us if the Terminal window shows NEW log messages while the freeze/stutter is happening. ** Changed in: gnome-shell (Ubuntu) Status: Confirmed => Incomplete ** Summary changed: - Gnome Shell pauses and stutters when under heavy load + Gnome Shell pauses and stutters while waiting (several seconds) for programs to launch -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1831369 Title: Gnome Shell pauses and stutters while waiting (several seconds) for programs to launch Status in gnome-shell package in Ubuntu: Incomplete Bug description: My laptop: HP 250 G6, Intel Celeron N3350, integrated video card, 4 GB RAM, Ubuntu 19.04 Details in my video: https://photos.app.goo.gl/ERUaSS6Qc8jFhHnn9 ProblemType: Bug DistroRelease: Ubuntu 19.04 Package: gnome-shell 3.32.0+git20190410-1ubuntu1 ProcVersionSignature: Ubuntu 5.0.0-15.16-generic 5.0.6 Uname: Linux 5.0.0-15-generic x86_64 ApportVersion: 2.20.10-0ubuntu27 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Sun Jun 2 14:32:17 2019 DisplayManager: gdm3 GsettingsChanges: b'org.gnome.shell' b'app-picker-view' b'uint32 1' b'org.gnome.shell' b'command-history' redacted by apport b'org.gnome.shell' b'favorite-apps' redacted by apport b'org.gnome.shell' b'enabled-extensions' b"['desktop-icons@csoriano']" b'org.gnome.desktop.interface' b'gtk-im-module' b"'gtk-im-context-simple'" InstallationDate: Installed on 2019-05-31 (1 days ago) InstallationMedia: Ubuntu 19.04 "Disco Dingo" - Release amd64 (20190416) ProcEnviron: LANGUAGE=ru_UA:ru PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=ru_UA.UTF-8 SHELL=/bin/bash SourcePackage: gnome-shell UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1831369/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
