This could be due to your graphic settings and graphics card. Please check your settings and check the manufacturer for updates to the graphics driver.

Thanks for your quick answer.

I forgot to mention that this is happening only in firefox. If im browsing with opera or IE everything looks great, as well as if i read some text document from word or smth...

I'll check for updates for graphic driver as you suggested, but i don't belive that it's the problem here.

Regards.

Try to disable hardware acceleration in Firefox.

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

• https://hacks.mozilla.org/2010/09/hardware-acceleration/

Try to set the gfx.content.azure.enabled pref to false or if this didn't help disable Direct2D by setting the gfx.direct2d.disabled pref to true on the about:config page and leave hardware acceleration otherwise enabled.

Thanks!

Looks like the first suggestion to turn off acceleration helped! :)

Thanks once again! ;)

DISTORTED TEXT * * * * * I have ATI Mobility Radeon HD 4200 Series, no updated driver available - Turning off Hardware Acceleration made no improvement. Problem began with Firefox 19.0.2 update! Does anyone know what the 'gfx.content.azure' config setting actually controls? and what results are to be expected?
