Adding of "options nvidia NVreg_PreserveVideoMemoryAllocations=1" into /etc/modprobe.d/nvidia-graphics-drivers-kms.conf and running "sudo update-initramfs -u" (not sure it's needed) + reboot helped me. Now when I resume my PC from the suspend mode, then a desktop wallpaper and menus/fonts are correct.
