Get image from Clipboard very slow in Linux platform. The picture less than 100K, but it takes about 10 seconds. But it's fast under mac.

Compiler Environment:
Linux archlinux 5.5.10-arch1-1
Qt version 5.14.1
cmake version 3.17.0

QClipboard *board = QGuiApplication::clipboard();
QImage img = board->image();
