iMac M4, macOS 26.3.1, Parallels 26 Pro, Debian 13.3. I changed resolution to full resolution in vm settings. From time to time resolution in Debian changes to 1024 x 768. I can change it to higher resolutions then. But iMac native resolution is missing from the list of choices. After some time this problem solves without me doing anything. What can I do?
