Rubber mousepads on glass desks are a pain.

Yes, rubber bases on glass can create suction or sliding, depending on the specific rubber and how clean the glass is.

Rubber sticks to smooth surfaces like glass. If the rubber is soft and sticky, it can form a vacuum seal — that suction. If it’s slightly harder or the glass is dusty, the pad might slide around instead. Neither is great for gaming or precise cursor work.

The fix is stupid simple: put a thin cloth or microfiber towel under the mousepad. That breaks the seal and stops sliding. Or swap to a pad with a non-slip silicone or foam base that’s designed for glass. Hard plastic or aluminum pads also work fine on glass — no grip issues.

Cleaning both surfaces with glass cleaner helps too, but that’s temporary.

Just don’t blame the desk. The pad is the problem.
