All maps colors were made much brighter on maps in hand, and all maps on item frames became partially transparent.

In particular, player held maps look really bad now – blue water don't look very blue (more like light purple), and it is hard to read.
Getting the same problem, using Win 7-64 and AMD HD6990 with cataclyst 13.4. Duplicates https://mojang.atlassian.net/browse/MC-35848
Not just brighter. All 18 of my map wall maps are no longer opaque. I can see the wood texture through them from the oak wood behind them.
