Resizing a window causes artifacts, as seen in this video: https://streamable.com/ityc8 video card info: GL_RENDERER = AMD JUNIPER (DRM 2.50.0 / 4.15.0-29-generic, LLVM 6.0.0) GL_VERSION = 3.0 Mesa 18.0.5 GL_VENDOR = X.Org This is a clean install of Kubuntu 18.04, live version also exhibited the same artifacts. moving the windows works fine, watching videos works fine, glxgears works fine. Only resizing of any window causes weird artifacts.
