So I have had this problem when every figure i exported using the openGL renderer has a black background which i did not want. I searched through the internet for a solution but never came across an answer. I thought I would post on here in case anyone else comes across this thread.

It appears that a setting has been unwillingly changed (although I dont know which one). My solution was to find the preferences directory by typing prefdir into the command line.

prefdir

Close matlab

Delete this folder

Re-open matlab.

The folder is recreated but not previous settings or history is used by matlab. It is quite annoying but it solved the issue with always having the black background with exported figures
