Texts are very blurry in many websites ( Youtube Notification Pannel )

[tz-shuhag]

Preliminary checklist

• [X] I have read the README
• [X] I have read the FAQs.
• [X] I have searched existing issues for my feature request. This is a new issue (NOT a duplicate) and is not related to another issue.
• [X] This is a feature request for the Cromite browser; not the website nor F-Droid nor anything else.

Is your feature request related to privacy?

No

Is there a patch available for this feature somewhere?

Texts are very sharp and clear when I open the notification tray of yourtube in Chrome. So yeah its available in chrome and other chromium based browsers ( brave, edge, opera, ungoogled chromium )

Describe the solution you would like

For now just turn off Viewport Size Protection from settings>privacy>site settings>Viewport Size Protection. In future this might get fixed with some updates.

Youtube Notification panel.

What is "Youtube Notification panel" ?

[tz-shuhag]

Well it got fixed when I disabled Viewport Size Protection

[tz-shuhag]

Youtube Notification panel.

What is "Youtube Notification panel" ?

notification slide in youtube.com

[uazo]

notification slide in youtube.com

there should be no notifications, can you take a screen shot please?

[tz-shuhag]

[tz-shuhag]

Texts in this panel was unclear and blurry before I turned off Viewport Size Protection from privacy>site settings>Viewport Size Protection

@abznidre thanks!

@PF4Public found a way to reproduce it!

[uazo]

@abznidre did you install chrome or brave?

[uazo]

@abznidre another thing, could you please show me WHERE that notification appears? i.e. could you please take a screen shot of the whole screen? of course blur anything you like. I'm telling you this because it never appears to me and I don't know what to look for in the source code

[PF4Public]

I'm telling you this because it never appears to me and I don't know what to look for in the source code

It is a little bell icon in the upper right corner of the page, near your account info. You need to be logged in, have any of your subscribed channels publish a video recently in order for notification to appear.

@PF4Public found a way to reproduce it!

Hope you can fix it at last!

[tz-shuhag]

@abznidre did you install chrome or brave?

No I am still using chromite

yes its that little bell icon

@uazo I found another related case of blurriness: network graph on GitHub

Observe that canvas has dimensions 691x480, but it is calculated as 690.990x479.995

[uazo]

No luck, I cannot reproduce it.

[leduyquang753]

Another place this happens is in the popup chat panels on Facebook, which creates borders around elements when a gradient chat theme is used.

(The message contents are not sensitive.)

[uazo]

can you tell me the resolutions of your screens?

[leduyquang753]

can you tell me the resolutions of your screens?

1920 . 1080.

[PF4Public]

@leduyquang753 What is the dpi of your screen?

[leduyquang753]

@leduyquang753 What is the dpi of your screen?

142 DPI.

[PF4Public]

@uazo I still think that it might be related to hidpi screens, do you have one for a test?

[uazo]

do you have one for a test?

142 DPI is same as me (see https://dpi.lv)

I cannot reproduce any except this https://github.com/uazo/cromite/issues/240#issuecomment-1709306234 which by the way is also detected by creepjs: I also realised that Disable get*ClientRects() fingerprint deception flag (chrome://flags/#fingerprinting-client-rects-noise) must remain deactivated by default, whereas it is now active by default. I will let you know.

[uazo]

some updates. first of all, I studied my patch, which I no longer remembered :)

then, the problems of text blurring is unfortunately insurmountable.

what the patch does is change the internal zoom of the dom elements, because the zoom factor is the value used to recalculate ALL the blink co-ordinates, and here the fact that the user is protected from fingerprinting scripts on the coordinates, which are ultimately based on screen geometry (at least in android). I'm trying to find out if there are any zoom factors that minimise blur, but so far I haven't found any. if someone wants to try, this is what needs to be changed https://github.com/uazo/cromite/blob/master/build/patches/Viewport-Protection-flag.patch#L582 the assumption is that there is a formula to derive that factor to minimise the blur effect, but I did not find it.

in relation to https://github.com/uazo/cromite/issues/240#issuecomment-1709306234 this is exactly how it works, i.e. 100px is no longer 100px but a little more or less. can be exploited to recognise cromite, but not the user, and in any case, it would not be so different from bromite (and ungoogled chromium) where the coordinates were 'dirtied' at random. The only thing I would like to fix is to make it more difficult to tie the user/browser to the ip, but that's another story.

in relation to https://github.com/uazo/cromite/issues/240#issuecomment-1857505851 what creepjs detects is the difference between the co-ordinates of a known rectangle (i.e. 0-0x100px-100px rotated by 45 degrees) and those exposed by the browser, but it is more a mechanism for detecting a lie rather than obtaining any information for fingerpriting the device, probably serves to detect whether the user is using a 'normal' browser, more related to anti-fraud systems

@PF4Public I found this by chance:

https://www.reddit.com/r/Cromite/comments/190hge2/blurry_fonts_in_cromite_on_certain_sites_sharp_on/

do not install anything, but could you try adding via devtools this css?

* {
  text-shadow: transparent 0px 0px 0px, rgba(0,0,0,0.1) 0px 0px 0px !important;
}

can you also change the 0.1 to some value? I would like to understand what happens with that css and I have no way to reproduce the blur

thanks!

[PF4Public]

do not install anything, but could you try adding via devtools this css?

I've added that to html element, no difference. Changing 0.1 to 999999999 makes no difference. Also by toggling this style on/off I cannot see any effect.

[uazo]

too bad. thanks for checking.

[PF4Public]

Maybe I should give that extension a try?

[uazo]

haha, you want my authorisation? only if on stamped paper :)

Maybe I should give that extension a try?

As you wish: I simply did not want to ask you to trust something that I do not know and that has no open code.

[PF4Public]

Why did you consider text-shadow should make a difference in the first place? Have you tried installing that extension, is it what it does? Maybe there is something else to check?

haha, you want my authorisation? only if on stamped paper :)

And only if it's notarized! :D

I simply did not want to ask you

That's kind of you! There are plenty of technical means of handling unknown/untrusted software.

[uazo]

Have you tried installing that extension, is it what it does?

no, I remind you that I don't have that problem (maybe I'm on the computer too much and don't realise it :) I opened the extension code and saw that it does just that.

Maybe there is something else to check?

not so far, I can't think of anything else.

[uazo]

Why did you consider text-shadow should make a difference in the first place?

Sorry, I forgot this. simply because that user said he solved it that way

Quote from extension description:

The windows browsers render the fonts based on the normal sub-pixel rendering without implementing Font smoothing

Perhaps this workaround works only on Windows? I tested on Linux.

@tz-shuhag can you try?

[Universalizer]

* { text-shadow: transparent 0px 0px 0px, rgba(0,0,0,0.1) 0px 0px 0px !important; }

RGBA = Red, Green, Blue, A = Apha (Transparency in percentage, here min. 0 to max. 1), change from 0.1 to 1

@tz-shuhag can you try?

Sorry to say no as I am also using linux at this moment. In windows I was easily able to overcome this problem by turning off Viewport Size Protection from settings>privacy>site settings>Viewport Size Protection.

I would recommend you to just keep viewport size protection off by default and not go on that much on this issue.

Android version of chromite is fantastic man. It's my default android go to browser.

lastly do you @uazo have any plan to build something like chrome os or fyde os. I am quite interested in Chromite OS 😀.

[uazo]

thank you @tz-shuhag I didn't think you were referring to linux.

I would recommend you to just keep viewport size protection off by default and not go on that much on this issue.

no, but thanks.

I am quite interested in Cromite OS

too many things to do first, maybe in a few years.

[uazo]

I finally found a way to reproduce the problem!

[PF4Public]

I finally found a way to reproduce the problem!

So, have you found a solution, is it fixable?

[uazo]

let's say I found a way to reproduce and investigate the problem. claim to be able to solve it, not yet.

[uazo]

for that specific situation the problem is opacity. values such as 0.999 lead to that effect:

@PF4Public can you verify it?

[PF4Public]

@PF4Public can you verify it?

I can confirm that disabling opacity makes text go sharper. This does not fix the issue with canvas though as it is independent of opacity.

[uazo]

thanks for the check.

This does not fix https://github.com/uazo/cromite/issues/240#issuecomment-1709306234 though as it is independent of opacity.

It is not possible to solve this problem, it is inherent in the way the patch works.

[PF4Public]

I understand

BTW, could 8998e3d be used for fingerprinting?

[uazo]

BTW, could 8998e3d be used for fingerprinting?

theoretically no, I checked. the value appears to the dom and javascript anyway as 0.99x but internally considered as 1.
