video: https://envs.sh/dPm.webm this is recorded in MiniBrowser from gnome-nightly, on https://developer.gnome.org where it's very visible, but it also happens on other websites and in Epiphany for me this only happens when power profile is set to power saving
I'm unable to reproduce this with Epiphany Tech Preview 45.alpha-5-g2486bfbdf+/ WebKitGTK 2.41.6

I've tried both Intel i7-9700/UHD 630 and Apple M2 Max (VM). I've tried all three power profiles.

You can find out by trying something like: diff --git a/Source/WebCore/platform/glib/LowPowerModeNotifierGLib.cpp b/Source/WebCore/platform/glib/LowPowerModeNotifierGLib.cpp index d380c2fbfab9..2ded0ce8bda8 100644 --- a/Source/WebCore/platform/glib/LowPowerModeNotifierGLib.cpp +++ b/Source/WebCore/platform/glib/LowPowerModeNotifierGLib.cpp @@ -28,13 +28,13 @@ namespace WebCore { LowPowerModeNotifier::LowPowerModeNotifier(LowPowerModeChangeCallback&& callback) -#if GLIB_CHECK_VERSION(2, 69, 1) +#if 0 : m_callback(WTFMove(callback)) , m_powerProfileMonitor(adoptGRef(g_power_profile_monitor_dup_default())) , m_lowPowerModeEnabled(g_power_profile_monitor_get_power_saver_enabled(m_powerProfileMonitor.get())) #endif { -#if GLIB_CHECK_VERSION(2, 69, 1) +#if 0 g_signal_connect_swapped(m_powerProfileMonitor.get(), "notify::power-saver-enabled", G_CALLBACK(+[] (LowPowerModeNotifier* self, GParamSpec*, GPowerProfileMonitor* monitor) { bool powerSaverEnabled = g_power_profile_monitor_get_power_saver_enabled(monitor); if (self->m_lowPowerModeEnabled != powerSaverEnabled) { @@ -47,7 +47,7 @@ LowPowerModeNotifier::LowPowerModeNotifier(LowPowerModeChangeCallback&& callback LowPowerModeNotifier::~LowPowerModeNotifier() { -#if GLIB_CHECK_VERSION(2, 69, 1) +#if 0 g_signal_handlers_disconnect_by_data(m_powerProfileMonitor.get(), this); #endif }
