Lag with git version, 11.2 fine #1330
Comments

Same here: picom (vgit-89c2c). My fading its very lagged too |

It's hard for me to visualize exactly what you mean, do you have a recording? And if you are sure 11.2 is fine, can you do a bisect to see at which point did it start happening? |

probably same problem as #1345, try the |
It now works fine |

Once again we found ourselves going into sleep while there are X events in libxcb's buffer. This time it's because both vblank_handle_x_events and x_poll_for_events can read from the X connection. This is introduced as part of commit d617d0b. Before that, we were only calling xcb_poll_for_queued_events after vblank_handle_x_events. By changing that to a xcb_poll_for_events (and later to x_poll_for_events, which calls xcb_poll_for_events), we could read additional vblank events into the buffer. These events will not be handled because vblank_handle_x_events has already be called, so we will be going into sleep with these events in the buffer. Since vblank events driver the frame render loop, this causes indefinitely long delay between frames. Related-to: #1345 #1330 Signed-off-by: Yuxuan Shui <yshuiv7@gmail.com>

Problem
I'm sometimes getting lag while switching workspaces, terminal is slower. For example ctrl + c in terminal is laggy, vim is slower, neofetch is taking longer to show. Very weird. GUI apps are fine I think. It's random. 11.2 release version is fine. No lag or slowdowns. This has been happening for some time now, at least since June.
