client resolution issue

i can play league of legends just fine , and whenever i decide to take a break and minimize the client , upon re-opening all i get is a small rectangle at the top left corner of my screen and its unfix able , i close the client and re-open it to have my resolution settings reset. i'm on 1920x1080 resolution btw. while this bug isn't exactly game breaking , it is still a pain every time i minimize the client for whatever reason , the client shrinks to a small rectangle and i have to close it then re-log and reset my resolution settings again. anyone else getting this lately?
