Browser zoom makes graph blurry

Open kmcnaught opened this issue 2 years ago • 6 comments

Description

If a user struggles to read small text (e.g. has a visual impairment or has dyslexia) then they might user browser zoom to get larger text. When you zoom in (Windows 10, Firefox 112.0.2 (64-bit)) the UI all scales correctly (yay!) except that the graph ends up really blurry.

Are you referring to the thickness of the graph line? I'm not sure what you mean by blurry.

This is the difference - it's like the graph has been rendered to a lower resolution.

Zoom = standard (100%) Zoom = 250%

Ah I see what you mean. It looks like the thickness of the line is what changes, the samping of the graph doesn't actually change, so it shouldn't impact gameplay- the samples are just more visible.

It's mainly the legibility of the text on the graph that seems problematic. Good to hear it doesn't affect gameplay.

Oh I didn't notice the text, this is an excellent point. @polytroper any idea why this might be happening?

Weird. Nothing immediately comes to mind, but blurriness aside it is going to be very tricky to manage this relationship since the complex layout of the cartoon-style text makes it very nontrivial to enlarge. I would expect zooming to have no effect on the size of that text, but I’m not totally sure why it makes it blurry.
