It didn't change anything, but I noticed that my graphic card was no longer detected: it's now called llvmpipe (LLVM 15.0.7, 256 bits). This detection problem prevents me from seeing animations, activating night mode and waking up from sleep mode. I'd already had this problem with my Nvidia card (https://forum.zorin.com/t/some-probelms-in-the-new-version-of-zorin-os-core/33467) but since I've switched to Intel, I don't know what to do.
