There is also a magnify feature you can try to have it zoom in, you can find this under Controller settings> bind some button > System > toggle magnifier
I did this for a diff app. And did a back paddle that I have to hold for 3 seconds
You can change how far you zoom in or out under the regular steamdeck settings > display > Advanced > magnifier scale
Will try this tomorrow since I am observing Lent! Thanks for the recipe!
