Try to open and close your video-setting menue (Hotbars and Menue shouldn't be fuzzy) -> should switch back to normal view again. This also works in case of ongoing blurrieness effect after fully recovered bloodloss (healthy).

Just a suggestion: This "fuzzy" graphical bug occured, after logging in close to a pinetree faceing it. maybe its depending on how close the next loaded visible textures are in your line of sight....

Edit: Same graphical issue on the main menue background after logging out from the server with a pinetree in my face ^^

Will try to add a screenshot next time.

Issue confirmed for v.114557.

More or less the same category, so I'll jump on your train.

Attached some screenshots made in khelm during sunrise.
Same room in both pics, sun is shining from the doorside of the room.

Sun shines through interior walls and doors, reflecting on the floor and the opposite walls.

Not that big kind of bug like torches shining through walls, but maybe related.

Edit: In my case, theres was no change in illumination while moving.
