dnast Posted January 20, 2011 Share Posted January 20, 2011 Yeah, I'm glad they didn't remove Panorama altogether. I've gotten quite used to quickly switching between tab groups with just a shortcut key. Link to comment Share on other sites More sharing options...
The_Decryptor Veteran Posted January 20, 2011 Veteran Share Posted January 20, 2011 People having problems with DirectWrite, do you have ATI cards? It seems Nvidia and ATI cards render the text differently, Nvidia cards have light sub-pixel colours while ATI cards have very strong colours, to the point where you get a very noticeable rainbow effect with a string of text like "llllllllllllllllllllllll" Edit: And when you're taking screenshots of it, use PNG as the file format, JPEG destroys the colour info on purpose (The human eye can't see it very well, so no point trying hard to save it) unless you change settings in the encoder.

Punio4 Posted January 20, 2011 Share Posted January 20, 2011 I have problems with directwrite, and yes, I'm using an ATI card. The colors are better in the latest nightly. However, I don't see this as a D2D/DirectWrite/Microsoft/GPU problem, because of one fact, and that is that text looks great on IE9 which uses it aswell.

alisalem Posted January 20, 2011 Share Posted January 20, 2011 I think sometimes IE9 uses ClearType instead of D2D, so you'd think it's rendering looks better. Link to comment Share on other sites More sharing options...

I don't see any colors or rainbow effect on my card, to mee the rendering is just way too blurry, especially with the lllllll example you posted. A lot of letters just look blurry/washed out compared to cleartype. You notice in cleartype the rendering looks very consistent, in Directwrite some letters look alright and others look very faint and blurry.

Strange thing is, I don't have that issue at work on the same version of FF4 (which is running on XP).

GDI is designed to render text to CRT monitors (it's from Windows 3), while DirectWrite is designed for LCD displays and as such doesn't have a lot of the limitations GDI does (ClearType is bolted onto GDI, while DW is designed around it) You get more accurate glyph rendering, more accurate inter-character spacing, and more accurate line lengths than you would with GDI (and it's much faster too). Compare this under GDI to DirectWrite, GDI simply can't scale and place the glyphs properly due to it's limitations. Link to comment Share on other sites More sharing options...

Well I have and lcd and think it looks like crap, it may "technically" be better but most people seem to share my opinion that it looks pretty awful lol. It does look better at large font sizes, but at normal font sizes it is pretty bad :/ Link to comment Share on other sites More sharing options...

Denis W. Veteran Posted January 21, 2011 Veteran Share Posted January 21, 2011 And here's an example from my laptop with Intel HD Graphics (also switched to the onboard discrete GeForce GT 335m and got almost identical results): Clearly there's a contrast difference. edit: The previous screenshot was captured on a machine without SP1, while this one does have SP1. Not sure if there might be a fix inside the service pack with regards to DirectWrite rendering. Link to comment Share on other sites More sharing options...
The_Decryptor Veteran Posted January 21, 2011 Veteran Share Posted January 21, 2011 ugh, confusing. I've always gotten the results shown in your second screenshot (pre-SP1 with an 8600GT), and I've only ever seen the results from the first screenshot on ATI cards (even a few Mozilla devs have the same issue). I wonder if it's due to the ClearType settings Windows use. Link to comment Share on other sites More sharing options...
Guest mattburles Posted January 21, 2011 Share Posted January 21, 2011 The plan is to release beta 10 the week of Jan 24. There will be a beta 11 the week of the 31st and RC to follow soon after. Got this from Mozilla. There are now 85 hard blockers :) Link to comment Share on other sites More sharing options...

The_Decryptor Veteran Posted January 21, 2011 Veteran Share Posted January 21, 2011 Yeah, it's Bug 626293. It's because they're now doing the compositing manually (Since D2D/DW refuse to), but they're getting the gamma wrong. Link to comment Share on other sites More sharing options...
Guest xiphi Posted January 21, 2011 Share Posted January 21, 2011 The ClearType settings also has an effect on it. I've tuned CT and restarted programs, and have gotten worse/better results depending on how it's tuned. Link to comment Share on other sites More sharing options...

+Majesticmerc MVC Posted January 21, 2011 MVC Share Posted January 21, 2011 That's because xp does not support directwrite Well I guess that'd be why then :p The ClearType settings also has an effect on it.

I wonder if the people having the problem are the ones that have used the ClearType tuner in Win7? Link to comment Share on other sites More sharing options...
Kirkburn Posted January 21, 2011 Share Posted January 21, 2011 I should point out that |||||||||||||||||||||||||||||| is not normal text. I don't think it's surprising that DirectWrite isn't designed around displaying those perfectly. In the previous comparison, iiiiiiiiiiiiiiiiiiiiiiiii was displayed next to it ... and it looked fine. It's still an unlikely collection of characters, but more realistic at least. Of course it's not ideal that |||||||| can look odd, but it's not the end of the world.
