Premiere Elements 12 Photoshop Elements 12 on what computer operating system.
If Windows, have you gone to the Display controls and tried to gain an visual advantage there.
"Make it easier to read what's on your screen" and then 100%, 125%, or 150%.
What are the current setting there now?
From what I have read your screen size is 13 inches and the resolution is 3299 x 1080.
What you describe is a known issue with regard to certain applications and readability of the workspace details.
Other than that, I believe that your 12 or 12.1 is what it is.
Is 1920 x 1080 as display resolution option for you?
I am not sure if 13.1 Update of 13 or the new 14 would offer any advantage. I have found 14 to have some harder to define places in the workspace and Welcome Screen than prior versions.
Please consider and supply more information.
