chromedriver issue on linux arm64 and x64 with selenium send_keys

[Timothy Lee]

We build headless_shell and chromedriver to use with selenium for completely headless arm64 and x64 systems and with chromium 102.0.5005.115 we end up with large delays when doing selenium send_keys to an input field. In the chromedriver log we get hundreds of repeated instances of the following for multiple seconds before the keys are actually sent to headless_shell:

   "modifiers": 0,
   "text": "n",
   "type": "rawKeyDown",
   "unmodifiedText": "n",

}

We build chromedriver with the following GN args:

 target_os=\"linux\"
 target_cpu=\"${ARCH}\"
 use_ozone = true
 ozone_auto_platforms = false
 ozone_platform = \"headless\"
 ozone_platform_headless = true
 headless_use_embedded_resources = true
 headless_fontconfig_utils = true
 use_bundled_fontconfig = true
 icu_use_data_file = false
 v8_use_external_startup_data = false
 enable_nacl = false
 enable_print_preview = false
 enable_remoting = false
 use_alsa = false
 use_cups = false
 use_dbus = false
 use_gio = false
 use_kerberos = false
 use_libpci = false
 use_pulseaudio = false
 use_udev = false
 rtc_use_pipewire = false
 v8_enable_lazy_source_positions = false
 use_glib = false
 use_gtk = false
 use_pangocairo = false
 use_x11 = false
 symbol_level = 0
 is_component_build = false
 enable_nacl = false
 use_kerberos = false
 is_debug = false

We are using the same GN args that we have used for more than  year to build headless_shell/chromdriver 88.0.4324.182 with no issue.  Any ideas on what could be wrong with the chromedriver build to cause the above send_keys issue?

I had the same problem as you with an arm64. But I use gn with very simple parameters.

target_os="linux"
 target_cpu="arm64"

My chromium version is 107.0.5304.114, I have not solved this problem so far.If you have already solved this problem, I would like you to help me.

thanks.
