Glossy hard pads are a gamble for optical mice.

Yes, it’s a compatibility issue — most optical sensors rely on surface texture to track movement, and glossy pads don’t provide enough contrast or detail.

Optical sensors work by taking microscopic snapshots of the surface and comparing them to detect motion. A glossy hard pad is basically a mirror. There’s very little texture to lock onto, so the sensor gets confused and the cursor spins out, drifts, or stops entirely. Laser sensors handle glossy surfaces better because they use coherent light that penetrates slightly deeper, but they’re not immune — especially on highly reflective or clear surfaces.

The only real test is to try your mouse on the pad before buying. If you’re shopping online, check reviews for your exact mouse model and the pad you’re considering. Some pads (like the Glorious Element or Razer Atlas) are designed with subtle textures that optical sensors can track, but many glossy glass or plastic pads are a crapshoot.
