Hello,

Android Studio's Tool Tip window shows up with a regular KDE decoration. Minimize button doesn't work. Maximize and close button do. It is suppose to be discarded by hitting Esc key.

1. Why does KDE adds decoration to it when upstream doesn't want to? When started in GNOME, decoration is added but no minimize or maximize buttons are added which solves the problem of minimize button not working.

2. When I start Android Studio the focus is on the main window and not on the tool tip. The focus should be on tool tip so that I can quickly discard it by hitting Esc. I suppose this is a problem with Android Studio and not with KDE.

Thanks.

By "tooltip" you mean some dialog?

Whether or not (disabled) buttons are shown are up to the used decoration ("look of the titlebar"), capability hints (if actually provided - just comparing GNOME is anything but reliable here) are partially ignored, because
a) it's a proprietary and largely unspecified protocol that a majority of clients (and notably Java) use "wrongly" and
b) you'll find this comment in KWin sources: // To quote from Metacity 'We support those MWM hints deemed non-stupid'

If the "tooltip" would be a modal dialog, it would be active (whenever the mainwindow would get it) - otherwise the client can freely pass around that.
Also please notice that the input focus is not strictly bound to the active window - a client could theoretically "steal" the input focus to the main window from its own active modal dialog.

Yeah, some dialog. It's just like KDE apps' Tip of the day which are common in PIM apps. Most other dialog seems to get the focus but not the Tip of the day dialog. IntelliJ Idea/Android Studio are open source[1]. I have filed a bug anyways.
