The bug I am having is that the screen is stretched and I am not able to fix it by reinstalling, reseting my graphic setting to default on radeon or completely re installing mc and repair from installer does not help either

Whenever I try to load in mc I am not able to view the screen as it seems to be stretched like hell, all I remember doing was minimising and reopening the game nd changing some graphic settings which I reset automatically and then re installed Minecraft completely.
