I was having the exact same texture pop. Having to press escape to refresh the textures. What worked for me is setting the character detail and world detail (can't remember if that is what it's called) down from 200% to 100%. After that, no more problems for the most part. I still get 'some' pop. But it doesn't require me…
Dark Forest Blessed Shield. White Icon. Dark Forest Blessed Blade. ETA: Both are working correctly, it doesn't read the shield as a weapon like the Gloomwrought Shield. You can transmute both and dye the shield.
