[Bug 1518623] [NEW] Letters missing in most programs

 

Public bug reported:

I thought this bug was fixed in Ubuntu 15.04, but now I am having it. It
is a nasty bug making Ubuntu useless, I must restart (at least this is
how it worked in previous version of Ubuntu) to get my computer back. I
do not know if there is a coincidence, but I started Firefox and then
the bug was triggered.
