Isn't this the ATI Catalyst 10.7 bug already discussed in bug 23842? BTW, every now and then I'm experiencing this too (same video drivers for me).
No, it's not the same bug. Read bug 23842 comment 39 and bug 23842 comment 40.
As I get this, the "missing characters bug" could be caused by a real wined3d deficiency (such as the one fixed by Henri with commit 5f2fcfdd6b3b7ab9c15d2c450a87527d13d144c8) but also by a driver problem, and Catalyst 10.7 drivers are affected (bug 23842 comment 25 to 30). I strongly believe this is the same bug as bug 23842 and ATI drivers are the culprit here, as everyone confirming the bug has Catalyst drivers version 10.7. You can try to downgrade ATI drivers to an older version and see if that fixes the problem.
