This isn't a bug but more a gameplay preference tweak that would benefit the experience of interacting with items & the in-game world.
Here are some rough examples I worked on.
{F203637} .63 edit WITH NO simulated depth of field. No other screen obscurity other than the Inventory tabs.
{F203630} .63 edit WITH simulated depth of field. No other screen obscurity other than the Inventory tabs.
{F203632} .62 edit WITH NO simulated depth of field. No other screen obscurity other than the Inventory tabs.
{F203636} .62 edit WITH simulated depth of field. No other screen obscurity other than the Inventory tabs.
