Hi, same problem here. Following experiment:
- I commented out nearly all of my main loop
- after that, I could receive the right button-pressed codes
- uncommented main loop ->> same problem again.
I am observing the same behavior. After a few hours of debugging, I've found that I'm able to retain the majority of my original main loop() commands, provided I insert a delay() call of at least ~200ms. With this, I don't see perfect interpretation of the IR signals, but at least half of them are received correctly. I'm wondering if it's a timing issue, where if the IR signal is received while the loop() function is processing other data, it somehow jumbles the result. This makes me curious if it is a performance issue or whether the IRremote library could be modified to halt other processing as soon as it starts receiving a signal. I'm not an expert with Arduino, but I would have thought an interrupt-driven event would do this anyway.
Does anyone have any suggestions?
As background, what I'm trying to accomplish is control of an LED strip using the FastLED library, then altering the LED sequence with an IR remote. So far all I've implemented is brightness control, but if I can get this working, there's a whole slew of features I'd like to add.
For reference, here's my code:

CRGBPalette16 currentPalette;
TBlendType currentBlending;
// set up global variable for tracking LED brightness, initially set to half-power
uint8_t brightness = 128;
#define BRIGHTNESS_INCR 16
#define IR_PIN 11 // Signal Pin of IR receiver to Arduino Digital Pin 11
/*-----( Declare objects )-----*/
IRrecv irrecv(IR_PIN); // create instance of 'irrecv'
decode_results results; // create instance of 'decode_results'
/*-----( Function )-----*/
