--- Comment #12 from Martin Gräßlin <mgraess...@kde.org> --- > So, could you please elaborate what you mean with "not based on a > scaled down > thumbnail"? Because https://community.kde.org/KWin/Window_Metadata > does not > explain it. Quoting our documentation: "When a thumbnail is required the window manager informs the application for which window and in which size a thumbnail is needed. In addition it passes a filedescriptor of a pipe to the application. The application renders the thumbnail and writes the rendering result into the pipe and closes the pipe once the rendering is finished." Which means: the application renders the thumbnail in the requested size. What that is: completely depends on application. E.g. a browser could just render a fav icon of open tab and the title. A contact application could render information about the selcted contact. A mail application could render a readable preview of the open mail. The important part is: the application is in control and it's not going to be scaled down. Readability is at the core. We are giving the thumbnail back to the application. -- You are receiving this mail because: You are watching all bug changes.
