The screen size changes when opening Minecraft. This changes happens randomly and seems to swing between 2 extremes. When the screen size is normal (smaller icons, hud, etc.) The safe area needs to be set to 100% and the arrows meet all four Corners nicely. Then it will randomly change size, 'zoom in' and it will require the safe area to be set to 0% with a noticable shift towards the top of the screen. When this is set it becomes difficult to exit menus such as the game settings or the player's inventory. Multiple clicks may be required to click on menu features near the screen edge. No changes to the GUI scaling were made. Randomly, the screen size will  back to "normal" and the safe area needs to be changed back to 100%. The attached screenshots are from 2 different sessions with no changes made to the settings between. The earlier set (20220903) shows the "normal" screen while the later is from later I'm the day.
