This is the dimmer malfunctioning. Simple as that.
This type of problem can usually be managed in one of two ways.
have one of the bulbs be incandescent
have a properly safety-listed "resistor block" (read: capacitor assembly) wired in parallel with the lamps. This mimicks an incandescent bulb in the way we aim to accomplish above, and uses less power,...

LEDs need a dimmer that is rated for LED’s thier current draw is so low old school dimmers usually have this problem. The on off function is probably capacitive “touch” the rolling ball is probably much like a mouse the ball drives the resistor (an encoder in mice).

As mentioned above, the cause is phantom (ghost) voltage most likely caused by using a twin active cable from the light to the switch. This can be fixed by either by replacing the cable with two sdi (single double insulated) cables or burning ghost voltage by adding a small load such as an iron core transformer in parallel with the light fitting.

This appears to be a fairly standard monochrome LED strip using 3528s. And I apologize, but I'm going to use Metric units because that's how they're specced.
The standard/common strip has 300 LEDs per 5 metres. This comes down to 3 LED per 2" segment. There are double density (600/5m) or half-density (150/5m) strips also.
This one is a "standard 300"...

Your LED strip has one resistor per 3 LEDs, which is the standard for a 12V strip. Each group of 3 LEDs is wired in series, with the resistor setting the appropriate current. All groups of 3 LEDs plus resistors are then wired in parallel.
White LEDs take about 3-3.6V each, so 3 in series mean 9-10.8V, with the resistor taking the rest of the voltage up to ...

Unfortunately 3528 is simply an industry standard package name. It means the LED components are 3.5 by 2.8 mm with a specific "footprint" that describes where the terminals and solder should go on a printed circuit board.
We can see in your photo that the polarity and voltage are specified and there are markings where the tape could be cut. There are three ...

Flickering is caused by the voltage conversion “driver”
The driver sets the correct voltage and current level. The problem with today’s led’s Is they can be just about any voltage. For instance I have some 4’ strips that fire at ~40v but need ~60v for full brightness, so you really need to find the specs to get the proper driver for your lights. But yes ...

Why this often doesn't work
The #1 reason this fails is that the ballas-- hold on. The #1 reason is that Feit Electric is a bunch of junk. Along with Utilitech and Lights of America, these are brands to be avoided. All of them use the "Chinese dumping" business model of disgorge staggering quantities of hastily built lights of cheap parts with little QA - ...

The Installation Guide contains important information and notes regarding the installation and operation of the InstantFit T8 lamps. Please note the important points below:
Philips InstantFit T8 LED lamps are suitable to replace T12 fluorescent lamps
Philips InstantFit T8 LED lamps require non-shunted G13 (medium bi-pin) lamp holders (tombstones)
Philips ...
