On wake from sleep the Mac Studio's Desktop picture is shown in actual resolution instead of stretched to fit screen. For example, a picture which is 2059 × 1371 is shown at that resolution on a 5K Retina screen and so only fills about 60% of the screen area. It starts with the picture positioned in the top left corner but sometimes moves down the screen. This behaviour does not change if the screen is scaled up or down – the picture size is also scaled.
Notice that icons on the Desktop are displayed in the correct position.
At the same time, the Dock is shown at the bottom of the picture instead of at the bottom of the screen.
Usually, the Desktop redisplays correctly. But increasingly, the only solution is to log out and in again.
This might be related to my other question on the Desktop picture Pref Pane.
See attached example which is a full screen capture i.e. command-shift-3 (with my personal details obscured):
