macbook pro 13'3 mid 2012 startup screen glitches

hi, my mb pro mid 2012 screen glitches on startup, the top quarter of the screen is black and the rest is has the logo. it works normally though and the screen is fine . i have its original hdd and a second SSD installed where the cd drive was.. osx yosemite 10.10.5.. any ideas ?

My thoughts are if it doesn't affect the computer at all why worry about it??

Have you set the boot disk to the correct drive in disk utility??? it might be hunting for the correct volume.

cause i want it to be like its supposed to be. i dont think anyone would wanna see the startup screen glitching. yes the SSD is my startup disk.. both my drives have osx installed on them , so i tried using the hdd as a startup disk but still the same, both drives do this so im guessing its something else. i really want it fixed
