Font Rendering Got Bad After 32.0 Update

After the recent update, the font started to get badly rendered. Kind of blurry with jagged edges and transparent parts. It used to be okay D:

Sometimes it becomes okay for a moment as I scroll down on pages, and sometimes when I stop scrolling, the font stays as it is; as if there are specific positions for the text to render properly. However, not all of the fonts are affected. Only the ones inside the scroll area.

On times that the font renders properly, the bookmarks font, title bar, and tab names are unaffected and still appear not-smooth. Same thing does not happen on other browsers. All my other system fonts look okay; it's really just Firefox.

Restarting Firefox = didn't work Restarting Computer = didn't work Tried setting up Clear Type = didn't work Tried enabling and disabling Hardware Acceleration on Firefox = didn't work Tried enabling and disabling the Graphics card itself = didn't work Tried just about all of the suggestions I found on Google = none worked Tried complete uninstall and re-install of Firefox 32.0 = didn't work

Graphics Driver are updated ~ Windows is updated ~

I'm using Windows 7 Ultimate 32 bit Graphics AMD Radeon HD 6800

I fixed it by downgrading to Firefox 31 which makes me sure that 32.0 is the culprit. As I was about to send the message on top; I tried downgrading as my last resort and it worked. Now I'm only sending this as a report. I am hoping you'll figure out what caused it because I am quite strict (OC) that everything in my PC must remain updated >_<; thus I want to use Firefox 32.0 as much as possible.

can you try with the catalyst beta graphics driver from catalyst 14.4 has been blocklisted for direct2d because of stability issues in firefox 32 (bug #984488).

more options

Try to create a new Boolean pref on the about:config page via the right-click context menu with the name layout.paint_rects_separately and set the value to true and leave hardware acceleration and Direct2D enabled.

  • layout.paint_rects_separately = true
  • gfx.direct2d.disabled = true

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

philipp's suggestion worked :) Thank you! I'm now using Firefox 32 and the fonts are all good. Installing AMD Catalyst beta 14.7 fixed it.

I am having the same problem with Firefox 33(I think it started with 32).

If I revert to Firefox 31, the fonts display as they should and they look great. I installed AMD Catalyst beta 14.7, but that didn't bring any luck!!

Only by downgarding the Firefox version, I am able to get the fonts render properly.

Any thoughts?

You can try to disable OMTC and leave hardware acceleration in Firefox enabled.

  • about:config page: layers.offmainthreadcomposition.enabled = false

Thanks for the quick help, but still nothing!! If there are some other things that I can try, please post it when you have time.

more options

Did you already try to disable hardware acceleration in Firefox?

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

more options

Nope, still nothing. I also tried with these settings, they don't change anything either.

   layout.paint_rects_separately = true
   gfx.direct2d.disabled = true 

Guess, I will need to revert to Firefox 31 and wait for this to be fixed sometime soon.

Can you attach a screenshot?

  • Use a compressed image type like PNG or JPG to save the screenshot
  • Make sure that you do not exceed the maximum size of 1 MB

You can check if ClearType is enabled system wide for all programs to make other programs like Firefox use it.

Vista: Control Panel > Personalization > Window Color and Appearance > Effects: "Use the following method to smooth edges of screen fonts" Win7: *Control Panel > Personalization > Window Color and Appearance > Fonts > "Adjust ClearType text"

I forgot to mention, ClearType is on system wide. I am attaching two screenshots, where you can clearly see the jagged edges on the fonts.

Also, I have a case of totally wrong rendering of one font(museo sans).

I know that I am not crazy, because if I downgrade to Firefox 31, both the jagged edges and Museo Sans render correctly.

I recently had a windows update yesterday and yes all of my drivers are updated but still nothing works. I even went through ClearType and resetting Firefox to no avail. Youtube's hyperlinks and Google's hyperlinks seem to be a bit blocky ever since. Disabling hardware acceleration did not work but I did find something that made it easier to see the fonts: - Go to your Firefox options and choose Content. - In Content choose advanced settings. - In Advanced settings, make sure to uncheck the box that says:

'Allow pages to choose their own fonts, instead of my selections above. After unchecking the box, click ok'

- I chose my own font preference (Georgia) and every page was reloaded with the changed setting. That made things look a little bit better. Note: This isn't the ultimate solution to this problem but rather a work around until SOMETHING is done. If this doesn't work for you, I'm sorry. :/

hello LadyLMarie, your issue is probably caused by this ms update: and not related to this existing thread. i'm closing this thread in order to avoid mixing up things. please ask a new question in case you still need help.
