Description
1.we build qtwebengine simple on wayland environment
simple code pushed to github: https://github.com/imaiguo/simplebrowser/
simple code from url: https://github.com/qt/qtwebengine/tree/dev/examples/webenginewidgets/simplebrowser
environment detail:
kernel:4.19.71-arm64-desktop
architecture:arm64
gpu:Mali-G76
libegl1:arm64 1.1.0
qt5wayland:5.15.4
wm:kwin-wayland
EGL interface: OpenGL_ES
OpengGLES version:2.0
main() add wayland support code:
qputenv("QT_WAYLAND_SHELL_INTEGRATION", "kwayland-shell"); QSurfaceFormat format; format.setRenderableType(QSurfaceFormat::OpenGLES); format.setDefaultFormat(format);
we open more than 1 tabpage,then close one tabpage ,simplebrowser crash happen

2.alter qtdeclarative code and simplebrowser code,now fix crash
change surface and buffer deleted order, close simplebrowser tab will not crash,but application exit will
so, i try to add code to application closeEvent and some code in qtdeclarative QQuickWidgetPrivate::invalidateRenderControl:
then everything is ok.but we need to alter code in qtdeclarative
commit detail:
https://github.com/imaiguo/qtdeclarative/commit/c32904a6a4f2e2351268eac5e57c626ac3ba2b83
then now another crash left: simplebrowser crash when close application windows
if i add blow code in application closeEvent,and estimate currentContext() is nullpter in then return in QQuickWidgetPrivate::invalidateRenderControl ,everything is ok: no crash happen.
if (QOpenGLContext *context = QOpenGLContext::currentContext())
{
context->doneCurrent();
}
commit detail:
if not add QOpenGLContext::currentContext() doneCurrent() in closeEvent(),application exit crash
crash gdb bt detail below:
