I have had this issue with the game for a long time, about a month, and it is just plane frustrating to deal with.  I could only play the game at a higher resolution if I use a modded client like curse forge, or I download a mod that allows my game to be in windowed borderless which solves the issue.  I have to say this is also only happening on full screen an not in windowed mode.  This does not happen in the bedrock version, and in many other games like Rainbow Six Siege and many other call of duty titles.  I have tried turning off and on vsync, which did nothing, and changing the fps slider to multiple different things to no avail.  When my fps is on unlimited, it will say the game is running over 60 fps, but my monitor is not running over 60fps.
