As far as i've experienced while playing, the game only displays the cursor during your turns and in the prologue and epilogue of the game, the cursor will be invisible during the dealer's turn for example. Devs may correct my information though it might be a different issue you're facing.
If you are using 2 monitors, try switching the game to the other one. I had this issue as well. Press Win+Shift+arrow key in the direction of the other monitor.
