    Description

      The new Vulkan rendering backend doesn't work well On Archlinux (kernel 6.1), AMD Polaris ,Mesa 23, Weston.

      Simplebrowser - there are no window decorations, font rendering is broken, on loading there are noise artifacts. Mouse over doesn't work correctly.

      Quicknanobrowser - there are no window decorations. Going to ddg.gg or chrome://gpu results in segmentation fault in libQt6Quick.so. There are noise artifacts. Using `QQuickWindow::setGraphicsApi(QSGRendererInterface::Vulkan);` results in segmentation fault (but not always). Websites that work with Simplebrowser segfault on QML.

      Also there is no example for the Vulkan backend for C++ or QML.
