I am running xubuntu 14.04 and recently got the weird effects shown in screenshot. Missing letters. Both in thunar and nautilus not firefox though. When I hover over name the letters fill in.

I've seen similar artifacts on Intel graphics cards with SNA acceleration method enabled. However, this became default a while back so if it is this, its interesting that you are seeing it only now.
What graphics card/driver are you using? This should help to identify it:
And out of curiosity, what is "recently"? Has Xubuntu 14.04 worked fine for a while then it started?Code:lspci -k | grep -iA2 VGA
here is the output. It started yesterday. I did a clean install of Xubuntu 14.04 64 bit about a week ago, thank you
Code:cmcanulty@ubuntu1:~$ lspci -k | grep -iA2 VGA 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) Subsystem: Hewlett-Packard Company Device 1439 Kernel driver in use: i915 cmcanulty@ubuntu1:~$
This works for some old Intel graphics cards. It may be worth trying also in your case (to switch from SNA to UXA acceleration)
If the command
gives the outputCode:lspci | grep -i vga
or similar from the 8xx family you need to create an /etc/X11/xorg.conf file with the following contents:Code:00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02)
There's a tab in front of the three middle lines.Code:Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" EndSection
Without the xorg.conf the resolution is coarse and Youtube videos are rendered in an interesting display of green and purple colours.
In 14.04 the bug is more or less fixed, but still you might get a nicer looking display using the xorg.conf. Try with and without, if there's no improvement just delete the file.
I get
Code:cmcanulty@ubuntu1:~$ lspci | grep -i vga 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) cmcanulty@ubuntu1:~$
You have another (probably newer) Intel graphics chip. I don't know if the UXA acceleration tweak will work for you, but it is worth trying.
