Yes, confirmed. The last two resolutions in your list, 1024x640 and 1440x900 are HiDPI resolutions. The first three are not.After the problem occurred, I installed SwitchResX and discovered the above resolutions were being set.In SwitchResX I was able to change the resolution to 1920x1200, but not in HiDPI. That choice is not in the list.What is your laptop model? I'm curious if this only happens with the discrete Radeon GPU, or if it also happens on the Iris Pro-only model.
