I have poor eyesight and for this reason I have enlarged scales configured both at the system level and at the browser level.
Most desktop applications and web sites in 2023 are DPI/scale/fonts-aware and are displayed acceptably with different visualisation features of client devices, work well and for the most part do not cause problems.
But not the VRChat site.
It is simply torn apart, as if falling into a black hole.
Please test your site with different DPI/scale/font emulation.
Below, a few screenshots of how terrible it looks to me.
