I switched back to using the Nvidia driver (450.51) after having used the intel driver with Nvidia offloading for a number of months. My problem is that after I sleep/resume, the systemsettings sidebar is black. Attempting to click in the area does nothing. Also, attempting to logout is either delayed for a minute or entirely unsuccessful. Disabling effects, switching rendering backends, and running 'plasmashell --replace' has no effect. The problem occurs with or without the use of nvidia's power management systemd unit files. The only thing that fixes it is to restart sddm or reboot. STEPS TO REPRODUCE 1. Set "Lid closed" action to sleep in "Energy Saving" 2. Close lid and open lid 3. Open systemsettings5 or try to logoff OBSERVED RESULT See https://www.youtube.com/watch?v=G7jIDrTaTSQ Operating System: Gentoo Linux KDE Plasma Version: 5.19.2 KDE Frameworks Version: 5.71.0 Qt Version: 5.15.0 Kernel Version: 5.7.6-gentoo OS Type: 64-bit Processors: 8 × Intel® Core™ i7-7700HQ CPU @ 2.80GHz Memory: 31.1 GiB of RAM Graphics Processor: GeForce GTX 1050/PCIe/SSE2

I've switched back to using the intel driver to render xorg-server. Though it seems that the issue doesn't show up, if I were to resume from sleep and then render systemsettings5 offloaded to nvidia (i.e., __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia __VK_LAYER_NV_optimus=NVIDIA_only __NV_PRIME_RENDER_OFFLOAD_PROVIDER=NVIDIA-G0 systemsettings5), it loads with the same black area. Rendered entirely with intel, there's no problem.
Same here. Resuming on proprietary NVidia drivers causes System Settings to show black rectangle instead of sections.

Tried suspend/resume with fresh KDE Neon (neon-user-20200827-0945) + Safe Graphics (Otherwise nouveau can not be removed easily after boot) and proprietary NVidia drivers. Everything works fine, no corruption. Seems like this bug is Gentoo-specific. I'll try to figure out what causes corruption.
Downgrade to nvidia-drivers-440-x solved this issue for me.
