The build is fine and it seems to start fine, but opening new windows like "open file" only produces a blank and black window. At running I see only this output, that is not clear if it is related QXcbShmImage: shmget() failed (88: Function not implemented) for size 1407600 (690x510) QXcbShmImage: shmget() failed (88: Function not implemented) for size 518976 (318x408) Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged. QXcbShmImage: shmget() failed (88: Function not implemented) for size 12000 (100x30) and at build time there is a new warning coming from the compiler /usr/include/qt5/QtGui/qtransform.h: In member function ‘QTransform& QTransform::operator=(QTransform&&)’: /usr/include/qt5/QtGui/qtransform.h:81:46: warning: ‘void* memcpy(void*, const void*, size_t)’ writing to an object of type ‘class QTransform’ with no trivial copy-assignment; use copy-assignment or copy-initialization instead [-Wclass-memaccess] 81 | { memcpy(this, &other, sizeof(QTransform)); return *this; } | ^ Anyone had similar problem with other programs ?
