[Virtual-pkg-base-maintainers] Bug#739825: base: font/image rendering problem (firefox, some overlays and others)/ scrambled look [gtk, qt?]

[Ernstesto Totalo]

Package: base
Severity: important

Dear Maintainer,

Some graphical areas appear to render incorrectly.
Instead of glyphs there are artifacts that have similarly-coloured pixels.
This appears to affect only a specific kind of text-field or icons.
Some applications seem to render most text correctly and some not.

As an example: Firefox does not seem to contain any readable text, whereas konqueror has no problems rendering web-pages and window-frames.
But an overlay in konqueror also has scrambled content.

I had the suspicion it was gtk, so i opened gimp to find most text (menubar/ tags) not working either, but a self-compiled application using gtk works fine.
Most KDE-related content appears to be rendering correctly also.

In another X session everything is alright and i guess restarting the computer would solve the problem (or rather: hide it).
I'm offering to leave this X session open for a week or so - just in case anyone is interested enough - to be able to provide further information on request.

This might be the second time i am experiencing this (in wheezy earlier, but not entirely sure) but i have no idea how to reproduce this.

I'm on a laptop, running KDE and have not properly re-started the computer for a day (standby/idle). Apart from that there should be nothing unual about my setup.
The problem renders a many of applications unusable, but the workaround is simple.

kind regards

P.S. as soon as i have worked out how to supply screenshots, i will. But i'd prefer sending them to individuals via email (silly paranoia).
