Buttons disappearing on hover using Firefox

[Game_Academy]

Hi everyone!
My company’s website has been released not so long ago, and we were using only Chrome during the developement.
So we didn’t test on Firefox and we just realized that we had a quite blocker problem : The menu buttons on the right panel sometimes disappear when hovering them. We know that disabling the animations and transitions on them kind of fix this, but we would like to know if there is a better solution.

Thanks for the help.
