Today, I emerged xfce4-meta, started XFCE4
and spent a short period of time within it.

For this short period of time, the "problem"
with rendering symbols in youtube video player
toolbar in google-chrome appeared in exactly
the same way as it appeared within Awesome WM.

I have also noticed the problem with rendering
letters in google-chrome. However, it appeared
a bit different: parts of letters in an html page
were closed by small black boxes, however not
everywhere but only on a side panel.

At the same time letters of a word written on a button
had exactly the same rendering problem as within
Awesome WM.

So, it seems that the problem is not specific to Awesome WM.

It seems to me that the problem is somehow related
to redrawing a frame. However, I am still not sure if
it is a problem of software or hardware.

I have not tried another google-chrome profile so far.
