The text editor "blurs" weirder

[ezShokkoh]

Hi,
This happens on every file I open on Notepad++, doesn’t happen on another text editor;
It starts “bluring” a little and goes in increase till it ocuppies half screen
This is kinda weird 'cause it happens when I’m:
1- Not scrolling, just reading/writing
2- When I’m using only the keyboard and not the mouse
3- When I select something (holding click) and scroll down to select more lines

I tried turning “Editing -> Smooth Font” on and off, and tried algo turning “Misc -> Use DirectWrite” on and off, but none of those worked.

Any idea/suggestion?
Apology for my bad english :P

You just need to turn off DirectWrite:

(1) If your PC has an Intel GPU controlled by “CMAA”, see also https://sourceforge.net/p/scintilla/bugs/2344/?page=3#143d/42d2/93f7

@rdipardo Did you see the OP’s tried algo turning “Misc -> Use DirectWrite” on and off, but none of those worked.?

My first thought was it’s a loose video cable though I don’t know why it only affects Notepad++.

@ezShokkoh - can you replace the monitor to see if the replacement has the same issue? The images look more like a hardware issue which causes the pixel level ghosting or video display artifacts. I’m not sure what’s special about Notepad++ that triggers it.

On a lark you could try downloading and running a portable copy of Notepad just to see if it has the same issues. This will give you something that would not have the plugins or other settings from your normal Notepad++ may be bothering the video display system.

DirectWrite uses the GPU. When the GPU cranks up the refresh rate (as at least one Intel device is known to do), the edit buffer gets redrawn over and over, at a speed that’s increasingly out of step with Scintilla. It’s happened at least once, and could reasonably be expected to happen again.

@ezShokkoh:

Especially since the original poster implied that English is not their first language, it is possible that the original poster did not notice or understand that Notepad++ must be completely closed and then started again for any change in that setting to take effect.

It’s not enough to toggle the DirectWrite checkbox. You must close and restart Notepad++.
