This is just an annoying bug, probably a quick fix but I haven't figured it out yet.
My launcher goes crazy, but only after opening the drop-down menu when selecting a profile.

As you can see in my attached images, the launcher looks quite normal at first.

But when opening the drop-down in the bottom left to change profiles, something weird happens...

Then, it gets even worse after selecting "edit profile."

I can guarantee this is at no fault of the PC itself, this only happens for the Minecraft Launcher. When I close it and re-open it, it goes back to normal, until I want to change profiles again.

Again, it's not a HUGE problem, but it is quite annoying. I think it's something wrong with my Java, but I'm not too sure. If anyone could help me out, that would be great! Thanks!
