WezTerm version

wezterm 20240203-110809-5046fc22

Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?

Yes, and I updated the version box above to show the version of the nightly that I tried

Describe the bug

When wezterm is activated, opening Mission Control will not smooth, but not when iterm2 is activated look like video: https://github.com/wez/wezterm/assets/18000037/abd02ea3-1442-4234-a091-ccfa25573854

I'm not entirely sure if this is a mac issue; I was unable to reproduce (M2 Macbook Pro)

oh, maybe my os is 12 (Macbook Pro Monterey), it's a bit old

I have the same symptom (noticed that Exposé is choppy when wezterm is running and otherwise normal) on the following machine:

Late 2019 16 inch MBP 8 core i9 CPU 32GB RAM 8GB AMD GPU

Sonoma 14.5

Tried playing with front_end: the same happens with Software, OpenGL and WebGpu.

Tried playing with preferred GPU on WebGpu: the same happens on both integrated Intel and discrete AMD.

Tried playing around with animation_fps in case that somehow infects some Cocoa thing system wide: no effect.

The easiest way to spot this behaviour is to slowly do Exposé with the touchpad (or to let it go fast with the keyboard shortcuts).

Anything I can do to extract more data or to debug further myself? Not immediately sure what and how to profile as the problem is probably some resource (locks? interrupts? shooting in the dark) contention on the system / hardware level.

[Rotonen]

As an additional piece of information, no such problems manifest themselves with an M2 Air for me. This further hints that the behaviour could be hardware specific.

Running a 2019 intel mbp here. This stuttering is very prevalent when on the integrated gfx card, but not on the discrete one. My guess is that something is re-rendering when the window moves, and mission control is triggering it on each frame. Probably obscured by beefier GPUs.

[Landaman]

This happens for me on an M1, so not Intel-specific

Can also confirm this issue. Macbook Pro 16 (2019), macOS 15.1, empty config.

The issue is very noticeable when the integrated Intel GPU is active. However, when System Settings -> Battery -> Options... -> Automatic graphics switching is turned off and the dedicated AMD GPU is active instead, it looks like the same issue is still present, but the effect is very subtle. You can still see a very slight stuttering when manually controlling the Mission Control animation by repeatedly moving your fingers up and down on a trackpad (I wanted to record and post a video, but the stuttering is not really visible there, sorry).

[emilmelnikov]

Tried to play with window_background_opacity and window_decorations, as suggested in https://github.com/wez/wezterm/issues/2669, and the issue went away.

Just for the reference, here is a relevant snippet from my config:

config.front_end = "WebGpu"

-- Make sure that the Intel integrated GPU is used.
local gpu = wezterm.gui.enumerate_gpus()[2]
config.webgpu_preferred_adapter = gpu
wezterm.log_info("gpu = " .. gpu.name)
-- INFO logging > lua: gpu = Intel(R) UHD Graphics 630

-- Either of these fixes the problem.
-- config.window_background_opacity = 0.999
-- config.window_decorations = "TITLE|RESIZE|MACOS_FORCE_DISABLE_SHADOW"

[Landaman]

Can confirm this also fixes the issue for me
