WindowThumbnail did some open GL operations, discarding old textures, in the GUI thread. Whislt it's not going to cause a threading issue (as updatePaintNode always ran when the main thread was blocked) we're not meant to mix threads with openGL contexts. It also seems to have a GL leak on nvidia, which was previously masked by the double delete fixed in https://git.reviewboard.kde.org/r/126131/diff/2/ It seems only one worked, and in the applied version we went with the wrong one. This patch makes use of QQuickItem::releaseResources to delete the GL textures on window change and destructor; it's then removed from stopRedirecting so that start/stop redirecting handles xcb on the GUI thread and updatePaintNode/discardPixmap is the GL stuff on the render thread. See http://doc.qt.io/qt-5/qquickitem.html#graphics-resource-handling REVIEW: 128763 BUG: 368066
Plasma Framework
Foundational libraries, components, and tools of the Plasma workspaces
Introduction
The plasma framework provides the following:
- QML components
- A C++ library: libplasma
- Script engines
QML components
org.kde.plasma.core
Bindings for libplasma functionality, such as DataEngine and FrameSvg, see @ref core.
org.kde.plasma.components
Graphical components for common items such as buttons, lineedits, tabbars and so on. Compatible subset of the MeeGo components used on the N9, see @ref plasmacomponents.
org.kde.plasma.extras
Extra graphical components that extend org.kde.plasma.components but are not in the standard api, see @ref plasmaextracomponents.
org.kde.plasma.plasmoid
Attached properties for manipulating the current applet or containment, see @ref libplasmaquick
libplasma
This C++ library provides:
- rendering of SVG themes
- loading of files from a certain filesystem structure: packages
- data access through data engines
- loading of the plugin structure of the workspace: containments and applets
See @ref libplasma.
Script engines
Provides support to create applets or containments in various scripting languages.
