When I click the launcher and brings me to the main screen of Minecraft but it keeps flashing constantly and its annoying and makes the game unplayable its only recently happened. But it happens on all versions I went back from most recent update to few versions back and all of them have the same issue just continues flashing for as long as I try to play it. I didn't recently buy Minecraft for the pc I've had it for about 6 years and this is the first time this has happened to me and I've tried uninstalling it reinstalling it and it didn't work I don't know why this is happening but I wanna play and getting quite tired of it and I've had this issue for about a month so nothing has fixed it as of yet.

Edit: I would post some video files of what is happening but I do not want to cause seizures
