100% CPU usage on non visible window
What Operating System(s) are you seeing this problem on?
Linux Wayland
Which Wayland compositor or X11 Window manager(s) are you using?
Hyprland
WezTerm version
20231017-091526-fec90ae0
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 window is non visible (i.e. in other workspace) and has highly changing content (i.e. btop) there's 100% CPU usage.
To Reproduce
- Open wezterm.
- Open some highly changing app (like top, btop, etc.)
- Change workspace.
- Check CPU usage.
Configuration
local wezterm = require 'wezterm'
local act = wezterm.action

local Font_size = My_font_size

local window_dims = window:get_dimensions()
local overrides = window:get_config_overrides() or {}
local Dpi = window_dims.dpi / 96
local Scale_factor_general = 7
local Scale_factor_x = window_dims.pixel_width / ( Scale_factor_general * 9 * Dpi )
local Scale_factor_y = window_dims.pixel_height / ( Scale_factor_general * 7 * Dpi )
local Scale_factor = Scale_factor_x
if (Scale_factor_y > Scale_factor_x)
then
Scale_factor = Scale_factor_x
else
Scale_factor = Scale_factor_y
end

then
Font_size = My_font_size

end

Also tried without WebGL. Same bug.

Seems not to be an issue anymore with that commit. Closing for now.
Nah... I knew I closed it too soon. It's just randomly started to suck whole thread again.
30-60s this appears in debug console, to suck whole thread
