I've been having some small issues with my MATLAB Live Editor.
On occassion I will notice that the text in the live editor is rather blurry and hard to read. it affects plots as well. See below:
When I click on the MATLAB Live Script and "focus" on the section that is fuzzy, all of a sudden the text becomes sharp. See below:
I only just started noticing this, but it may have been occuring since I recently switched to a new computer. I know I never noticed it on my last PC. I thought perhaps it might be some kind of display or graphics setting on my new fancy GPU, but I am unsure. Does MATLAB have any recommended settings for the NVIDIA Control Panel?
I am running MATLAB Version 9.9.0.1495850 (R2020b) Update 1 and my PC has the following hardware:
OS: Windows 10 Po 20H2 - Build 19042.630
CPU: Intel i9-10920x
RAM: 128 GB Corsair LPX
GPU: NVIDIA GeForce RTX2070 Super
MOBO: Asus X299X AUROUS PRO
Display 1: LG 27UN850-W
Display 2: LG 27UN850-W

In my case, whatever I do by applying suggested solutions from the Internet are not working.
The only way to fix the issue is just simply disabling the FXAA and all edge smoothing items in the 3D setting of the Nvidia control panel.( Right click on screen) for my Nvidia RTX4000 card.

Double checked and you are right. Disable the FXAA is enough.

Hi Charles Refvem,
This issue has been brought to the notice of developers. They may investigate further.

In my case (see comments on first post) it has something to do with the Matlab help. When I open Matlab, all the text is depicted sharply and as it should be. BUT: As soon as I open Matlab help the font becomes fuzzy. When I close the help window, the problem persists.
My solution: Restart Matlab and use the Matlab help on the internet.
