Fedora 32 + nVidia graphic artifacts on resume

Hello all, after resuming from standby, many applications seem to omit repainting or refreshing areas of the screen. The system seems stable overall: applications keep running correctly, but I can't see important areas on the screen. For example, I might be able to open my email inbox, but then I can't archive an email as the area where the control buttons are supposed to be is entirely white (or black, in other applications). Or, someone pings me on IM - I can see the text but I can't reply as the reply area isn't there... you get the idea, it's annoying :) I've seen this happening both when using Gnome and when using i3. Since I'm running the nvidia proprietary drivers I'm assuming this is not related with Wayland, more likely some optimisation of the nvidia driver or how it integrates with X ? Would anyone have a suggestion as to how to debug this further, or a possible workaround? Maybe some nvidia driver option I could pass on the kernel, or in the X config file? I'd highly appreciate solving this, as it's my primary development machine: having to close all applications for frequent reboots has become very inconvenient. Unfortunately I can't easily roll back some update: I had this problem for many weeks, as initially I dismissed it as "just a glitch"; I had not paid enough attention to it and hadn't noticed that it was related to resuming from standby. This is what I'm running today: - linux 5.8.6-201.fc32.x86_64 - nvidia 450.66 Thanks! Sanne
