However, QGLXContext only tracks it per-context +using the m_swapInterval member. If a new drawable is made current to a +context, it is still necessary to call glXSwapIntervalEXT to change the +swap interval, even if it has been previously called for the same +context with a different drawable. However, currently, +QGLXContext::makeCurrent doesn't do this if its m_swapInterval field +matches the new swap interval. This change removes m_swapInterval from +QGLXContext, instead tracking it in QXcbWindow. This still avoids +unnecessary calls to glXSwapIntervalEXT, while ensuring the swap +interval is always set for new window drawables. + +Change-Id: Idc34101476c6af618059f6f3d8925dee743994a3 +Reviewed-by: Giuseppe D'Angelo +Reviewed-by: Laszlo Agocs +--- + .../platforms/xcb/gl_integrations/xcb_glx/qglxintegration.cpp | 6 +++--- + src/plugins/platforms/xcb/gl_integrations/xcb_glx/qglxintegration.h | 1 - + src/plugins/platforms/xcb/qxcbwindow.h | 4 ++++ + 3 files changed, 7 insertions(+), 4 deletions(-) + +diff --git a/src/plugins/platforms/xcb/gl_integrations/xcb_glx/qglxintegration.cpp b/src/plugins/platforms/xcb/gl_integrations/xcb_glx/qglxintegration.cpp +index 4adf662152..f26f698e76 100644 +--- a/src/plugins/platforms/xcb/gl_integrations/xcb_glx/qglxintegration.cpp ++++ b/src/plugins/platforms/xcb/gl_integrations/xcb_glx/qglxintegration.cpp +@@ -204,7 +204,6 @@ QGLXContext::QGLXContext(QXcbScreen *screen, const QSurfaceFormat &format, QPlat + , m_shareContext(0) + , m_format(format) + , m_isPBufferCurrent(false) +- , m_swapInterval(-1) + , m_ownsContext(nativeHandle.isNull()) + , m_getGraphicsResetStatus(0) + , m_lost(false) +@@ -567,9 +566,9 @@ bool QGLXContext::makeCurrent(QPlatformSurface *surface) + + if (success && surfaceClass == QSurface::Window) { + int interval = surface->format().swapInterval(); ++ QXcbWindow *window = static_cast(surface); + QXcbScreen *screen = screenForPlatformSurface(surface); +- if (interval >= 0 && m_swapInterval != interval && screen) { +- m_swapInterval = interval; ++ if (interval >= 0 && interval != window->swapInterval() && screen) { + typedef void (*qt_glXSwapIntervalEXT)(Display *, GLXDrawable, int); + typedef void (*qt_glXSwapIntervalMESA)(unsigned int); + static qt_glXSwapIntervalEXT glXSwapIntervalEXT = 0; +@@ -588,6 +587,7 @@ bool QGLXContext::makeCurrent(QPlatformSurface *surface) + glXSwapIntervalEXT(m_display, glxDrawable, interval); + else if (glXSwapIntervalMESA) + glXSwapIntervalMESA(interval); ++ window->setSwapInterval(interval); + } + } + +diff --git a/src/plugins/platforms/xcb/gl_integrations/xcb_glx/qglxintegration.h b/src/plugins/platforms/xcb/gl_integrations/xcb_glx/qglxintegration.h +index be9d3f5dcb..2a88fd6e59 100644 +--- a/src/plugins/platforms/xcb/gl_integrations/xcb_glx/qglxintegration.h ++++ b/src/plugins/platforms/xcb/gl_integrations/xcb_glx/qglxintegration.h +@@ -87,7 +87,6 @@ private: + GLXContext m_shareContext; + QSurfaceFormat m_format; + bool m_isPBufferCurrent; +- int m_swapInterval; + bool m_ownsContext; + GLenum (APIENTRY * m_getGraphicsResetStatus)(); + bool m_lost; +diff --git a/src/plugins/platforms/xcb/qxcbwindow.h b/src/plugins/platforms/xcb/qxcbwindow.h +index f98cd8a74d..8258cc2dfa 100644 +--- a/src/plugins/platforms/xcb/qxcbwindow.h ++++ b/src/plugins/platforms/xcb/qxcbwindow.h +@@ -184,6 +184,9 @@ public: + static void setWindowTitle(const QXcbConnection *conn, xcb_window_t window, const QString &title); + static QString windowTitle(const QXcbConnection *conn, xcb_window_t window); + ++ int swapInterval() const { return m_swapInterval; } ++ void setSwapInterval(int swapInterval) { m_swapInterval = swapInterval; } ++ + public Q_SLOTS: + void updateSyncRequestCounter(); + +@@ -276,6 +279,7 @@ protected: + SyncState m_syncState = NoSyncNeeded; + + QXcbSyncWindowRequest *m_pendingSyncRequest = nullptr; ++ int m_swapInterval = -1; + }; + + class QXcbForeignWindow : public QXcbWindow +-- +cgit v1.2.1 + -- cgit v1.2.3
