I quit runescape 7 years ago, and recently came back after playing some oldschool runescape. A regular problem I keep getting is all the textures in the game turn solid black, or occasionally solid blue, whenever I minimize runescape/switch windows on my pc. Only the sky shows anything at all. When I lodestone/teleport away, the map loads and it's back to normal. The cpu/memory is usually around half with chrome running as well. I tried this on two separate computers, an older computer and a G3 dell gaming laptop, and it is exactly the same. I can't even check the wiki while playing because of this. Any assistance?
