Package: mutter-common Version: 3.38.2-1 Severity: important Tags: upstream X-Debbugs-Cc: kamil.wilc...@protonmail.com
I have an nVidia GTX 1650 GPU and installed weekly testing system with GNOME desktop. * nouveau is basically unusable, it displays the desktop, but lags heavily and simple tasks, like editing a file in Vim is impossible, keyboard strokes are missed, or unwanted symbols appear (multiple letters are added or several letters are removed after single backspace press). So I installed nvidia-driver (currently 450.80.02) from non-free. I had to do it from a TTY, otherwise it was impossible. After reboot Wayland was still enabled (as default). Performance was great, but after a moment gnome-shell crashed, rebooted itself, then, for example gnome-terminal was lagging, some windows too (not often). This was in the logs just before the crash: gru 15 21:33:35 wilk gnome-shell[1438]: Can't update stage views actor overviewGroup is on because it needs an allocation. gru 15 21:33:35 wilk gnome-shell[1438]: Can't update stage views actor overview is on because it needs an allocation. gru 15 21:33:35 wilk gnome-shell[1438]: Can't update stage views actor Gjs_ui_overviewControls_ControlsManager is on because it needs an allocation. gru 15 21:33:35 wilk gnome-shell[1438]: Can't update stage views actor overview-group is on because it needs an allocation. gru 15 21:33:35 wilk gnome-shell[1438]: Can't update stage views actor Gjs_ui_overviewControls_ThumbnailsSlider is on because it needs an allocation. gru 15 21:33:35 wilk gnome-shell[1438]: Can't update stage views actor Gjs_ui_workspaceThumbnail_ThumbnailsBox is on because it needs an allocation. gru 15 21:33:35 wilk gnome-shell[1438]: Can't update stage views actor Gjs_ui_workspaceThumbnail_WorkspaceThumbnail is on because it needs an allocation. gru 15 21:33:35 wilk gnome-shell[1438]: Can't update stage views actor ClutterActor is on because it needs an allocation. gru 15 21:33:35 wilk gnome-shell[1438]: Can't update stage views actor Gjs_ui_workspaceThumbnail_WindowClone is on because it needs an allocation. gru 15 21:33:47 wilk gnome-shell[1438]: Window manager warning: MetaSyncRing: Sync object is not ready -- were events handled properly? gru 15 21:33:58 wilk /usr/libexec/gdm-x-session[1322]: (II) event5 - SteelSeries SteelSeries Sensei 310 eSports Mouse: SYN_DROPPED event - some input events have been lost. gru 15 21:33:58 wilk /usr/libexec/gdm-x-session[1322]: (EE) client bug: timer event5 debounce: scheduled expiry is in the past (-877ms), your system is too slow gru 15 21:33:58 wilk /usr/libexec/gdm-x-session[1322]: (EE) client bug: timer event5 debounce short: scheduled expiry is in the past (-890ms), your system is too slow gru 15 21:34:03 wilk /usr/libexec/gdm-x-session[1322]: (WW) NVIDIA: Wait for channel idle timed out. gru 15 21:34:04 wilk gnome-shell[1438]: Window manager warning: Failed to start restart helper: Wykonanie procesu potomnego (child process failed) „/usr/libexec/mutter-restart-helper” (Nie ma takiego pliku ani katalogu) się nie powio> (no such file or directory) gru 15 21:34:04 wilk gnome-shell[1438]: Window manager warning: META_CURRENT_TIME used to choose focus window; focus window may not be correct. This is not a keyboard/mouse issue. I used both on two other computers without problems (gnome-shell 3.36) or on Intel integrated GPU. I also connected a different keyboard to this machine with the same effect. I switched to Xorg (WaylandEnable=false in /etc/gdm3/daemon.conf). Performance is good, but there are issues unfortunately: * gnome-terminal is lagging, I have to wait for a cursor to move sometimes, it can hang even for a second or two. * I have to wait for a response from simple, usually immediate programs like htop, sometimes quitting is lagging to, quittin vim, etc. * switching between terminal tabs also hangs sometimes for a moment. * Not all programs are affected, browsers are fine mostly (I had one issue, but couldn't reproduce). I checked KDE and as far as I know it is unaffected at all. I only experience this on GNOME. I tried xterm instead of gnome-terminal, it seems unaffected. I wrote this report using reportbug-gtk and I had some problems with lags (waiting seconds for Enter to kick in, etc.), same in gnome-terminal. Scrolling sometimes hangs too. libinput messages about compositor being slow are appearing in logs. Similar problems were reported on GNOME's Gitlab, it looks like only some programs are affected. https://gitlab.gnome.org/GNOME/mutter/-/issues/1561 https://gitlab.gnome.org/GNOME/mutter/-/issues/1516 Someone in those issues pinpointed this behaviour to mutter, that is why I'm reporting this as a mutter issue (I also consulted #debian IRC before submitting here). This issue basically makes terminal annoying to use, and sometimes unusable. Stuttering and hanging is a no go for a programmer or a system administrator (like me), who depends on terminal (I use gnome-shell). I'm happy to help more, but I could use some help on how to debug more. I did some things mentioned in those Gitlab issues (DEBUG mutter, etc.) and check logs, etc., but the only relevant information that appear in logs is related to libinput and system/compositor being slow.
