So I play osu! using a tablet, and I started dragging because I found that I'm too shaky to accurately hover. After a while I realized that dragging wasn't the best for my tablet, and I tried using paper underneath my tablet pen to reduce tablet damage. I hated it so much because my tablet gives off the most cringe sound when I played. I started to use the plastic side of a card sleeve, and I have been playing like that for a couple of months. After an intense jump map I saw that the plastic on the sleeve was dying, so I replaced it with a new one. On the new one I found that these little "bubbles" form on my sleeve, which is basically a speed bump on my tablet, messing me up. Does anyone know a way to prevent this, or alternate ways to reduce tablet dragging damage?
Short Version
I use the plastic side of card sleeves for faster and smoother dragging. Bubbles form on my card sleeve when I drag, how do I stop it? It's handicapping me.
