Ghosting after Surface Pro 4 screen repair

Hi folks,

Two moths ago, I replaced my SP4 screen with the iFixit part and I recently began to experience screen ghosting.

Symptoms are

• It generally starts a few minutes after startup (temperature related?)
• Every other line of the screen is ghosting, the other is fine.
• Ghosting is strong at the center and non existent at the edges (vignette-like effect).

Any experience with that?

Cheers,

J
