* macOS: Flush sublayers via separate IOSurface backingstoresTor Arne Vestbø2020-03-251-24/+59
| | | | | | | | | | | | | | | | | | | | | | | | Flushing sublayers via QImage copies of the root IOSurface was causing performance regressions due to the constant allocations of new images each frame. We now re-use the QCALayerBackingStore implementation for sublayers, which gives a dynamic swap-chain. We're still paying the CPU cost of the copy from the root backingstore to the layered backingstores, as well as the memory cost, but at least improves the situation. We do not try to be smart and paint directly into the sublayers, as that would leave the root backingstore stale, potentially causing glitches when views are repositioned. Investigating this is left for future work.

* macOS Don't throw away backingstore buffers when backing properties changeTor Arne Vestbø2019-12-231-19/+17
| | | | | | | | | | | | | | | | | | Clients such as QtWidgets that do their own dirty tracking will assume they can just flush in response to the expose event, without repainting anything. Since we have no way at the moment to inform these clients that the backingstore content might be invalid we can't just throw it away. It turns out that to pick up changes in color spaces we can just tag the existing buffers with the new color space, so we don't need to throw it away. And for the older surface-backed mode we tag the color space on flush, so we didn't need to invalidate anything in the first place.

| * macOS: Respect color space set on NSWindow when flushing backingstoreTor Arne Vestbø2019-07-261-11/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default Qt tries to avoid potentially costly color matching by not assigning an sRGB color space to our backingstore, even if that's what we in practice fill it with. We used to do this by assigning the display's color space, which effectively opts out of color matching, similar to the old behavior of the device RGB color space (which nowadays implies sRGB). By picking up the color space from the NSWindow instead, we allow the user to override the color space to trigger color matching, for example by explicitly setting it to NSColorSpace.sRGBColorSpace. NSWindow will fall back to the screen's color space if the window doesn't have one set.

* | macOS: Track screens via Quartz Display Services instead of NSScreenTor Arne Vestbø2019-05-131-12/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | Using NSScreen as the basis for tracking screens is not recommended, as the list of screens can be added, removed, or dynamically reconfigured at any time, and the NSScreen instance, or index in the NSScreen.screens array may not be stable. Quartz Display Services on the other hand tracks displays via a unique display ID, which typically remains constant until the machine is restarted. The lower level API also gives us earlier callbacks about screen changes than the corresponding NSApplicationDidChangeScreenParametersNotification does. By reacting to screen changes _before_ AppKit does, we can remove workarounds for receiving window move and screen change notifications before the screen was actually visibly reconfigured. The new approach also handles changes to the primary screen, which can happen if the user moves the menu bar in the macOS display arrangement pane. The device pixel ratio of the screen has been made into a cached property, like all the other properties of QCocoaScreen. This is more consistent, and allows us to qDebug the screen even when it has been removed and we no longer have access to resolve the properties from the associated Quarts display.

* macOS: Add IOSurface based backingstore for layer-backed viewsTor Arne Vestbø2019-03-141-108/+435
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The naïve approach used for layer-backing in the past caused a detach of the backingstore QImage on each beginPaint, since the image was assigned to the layer via a CGImageRef that participated in the QImage implicit sharing (and had to, so we couldn't get around that). We now use IOSurfaces, wrapped in a QPlatformGraphicsBuffer abstraction. The surfaces can be assigned to the layer's content the same way images could, but allows us to reason more closely about whether or a buffer is in use, and increases the chance that we will have a zero-copy path to the screen. Unless the window has requested a surface format with single buffering we use a dynamic swap chain of buffers. In most situations there will be two buffers in play, one assigned to the layer and one ready to paint to, but during resize and some other situations the buffers will grow temporarily to accommodate the increased back-pressure. Since QBackingStore is documented as having single-buffer behavior, we take care to persist content between the buffers before every swap. By doing this before swapping, instead of before each paint, we can avoid preserving areas that will be painted to anyways, and will in many situations (such as blinking cursors e.g.) end up not persisting anything. The RasterGL surface case is handled by reading out the buffer data and doing a manual texture upload. In the future we can support direct texture access via CGLTexImageIOSurface2D, but this requires QPlatformBackingStore::composeAndFlush to learn how to support other targets than GL_TEXTURE_2D, as CGLTexImageIOSurface2D only works with GL_TEXTURE_RECTANGLE_ARB targets.

* Cocoa: Fix backing store performance regression.Morten Johan Sørvig2015-08-251-0/+2
| | | | | | | | | | | | | | | | | Commit 916dfcb8 introduced a regression where QNSView would hold a copy if the backing store QImage, which would cause a detach and deep copy if/when the image was painted on while the copy was held. Revert back to the previous share-by-pointer scheme.

| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>
* OS X - Cocoa backing store and drawRectTimur Pocheptsov2014-10-281-13/+0
| | | | | | | | | | | | | | | m_backingStore pointer has a limited 'lifetime' - usually it is set in -flushBackingStore:region:offset: method, then -drawRect: is invoked/forced by -setNeedsDisplayInRect:, after that it's dangerous to have a non-null pointer to a backing store (and we reset it). But if Cocoa invokes drawRect (due to some reason) our null backing store pointer is also not good. This patch instead is using a shared resource (QImage) from a backing store. This patch also makes getBackingStoreCGImage() redundant - -drawRect: was the only place we called it.
