Gradient Lughtstrip PC

Hello,

I installed a hue gradient lightstrip behing my pc monitor and paired it with hue sync and my bridge.
The first day was perfect, but on the nexr day, the transitions in color becaming slower and not smooth at all, making it jump from one color to another with a smooth transition.
Does anyone encountered this type of problem and know how to ix it ?
I already tried to reset my hue bridge, my gradiant lightstrip, uninstalling hue sync on my pc and then reinstalling it …
