Trying to install latest kde version. Intel I5 9300H / 16Gigs ram / Nvidia Optimus setup Intel UHD 630 - Nvidia 2060m. After boot into live disk desktop and bar has no icons. I can see the sub text for the icons and hover where they should be but cant see. Can hover over menu/favorites and click terminal but it takes 10 - 15 minutes to open. On latest Kubuntu it does the same but after install it's fine. Managed to get Siduction installed even though system is hanging constantly. After reboot into installed system same issue and if I click anything it freezes for 10 plus minutes.The only thing using resources is plasma. Tried updating and installing nvidia drivers but after reboot no desktop at all. The XFCE live version is fine. Any ideas or direction to look?
