I know you think you're right about everything, but you're not. LEDs do sometimes go into flickering mode.

Now, show us a link where the emitter is the cause of the flicker, and not the driver.

Oh, it happens; I've had multi-LED panels where handling the PC board (not the power
brick) caused/stopped the flicker. Not solder, either, some kind of internal-to-the-LED
package or thermal fault. Replaced four or five elements, and the lamp works fine now
(though my replacement LEDs were a mismatch for the original 'warm' white).
