We are observing from the new Firefox 55 that is sending through kwin too many windowChanged events when the mouse is just hovering over webpages... this wasnt happening with Firefox 54. is that normal? or firefox broke something?
what is a "windowChanged" event?
sorry Martin, I meant signal, https://api.kde.org/frameworks/kwindowsystem/html/classKWindowSystem.html#aa3c6faf243ef8faa9fb0d9c98bc5ca25
and which properties are changed?
It is changing, NET::WM2IconPixmap in every mouse hovering
Oh... and also NET::WM2OpaqueRegion in every mouse hovering in webpage especially in its startup screen
Ohhhh... this is serious... if you search something with google the results page from firefox creates an endless loop of signals like mentioned here and makes kwin to high cpu usage...
These are both properties set by Firefox and not by the window manager. The window manager only listens to changes. Sorry, but from our side there is nothing to do, we cannot do anything about Firefox sending those changes. Please report to Firefox.
