I have the opposite problem

, but maybe I can suggest something useful.
Don't try to see it all at once; if you have to learn one chord, reading each note one at a time (for now!), so be it. I don't know what in particular is giving you trouble, but suppose it's a succession of big nasty chords, full of accidentals. Learn (memorize) the first chord. Learn the second chord. Practice moving from one to the other. Etc. When you've practised all the moves enough, your hands should automatically flow in the right places. At this point (ideally) you will not be seeing each chord as a group of individual notes; instead you will remember the feeling of the chord as you see it. Does this make sense to you?
And in the meantime, work on pattern recognition. Note-by-note reading slowed me down for years.
Hope this helps.
