view port edge deformation glitch in 2.9 just downloaded the 2.9 and started doing some stuff but i noticed that some wiggly zig zag glitch is happening with the viewport , all the meshes in the viewport are getting glitched in the edges , here see some pics

no such problem in wireframe
Reduced the view clip distance. This is a floating point rounding error because your view clip range is too broad - @Gorgious
