Krangled text directly after game start (memory corruption maybe)

I do not know if this is the "Jumbled Text" issue from the Known issues.
If it is, please add more details there. That description gies no info at all...

What is the issue
Some item stack numbers in the stash tab do not display as numbers.
Examples:
- There are 4 Splinter of Xoph in my fragment tab and they show quantaty as ":".
- 78 is shown as "=>"
- 46 is shown as ":<"
- 47 is shown as ":="
- 66 is shown as "<<"

Assumption
Looks like the font itself got krangled and shifted 6 indices up.
(Just checked in ASCII table.)

How to reproduce
- Happens sporadically.
- Sometimes after start of game, sometimes in the middle of maps.
- Sometimes goes away randomly. (I think)

How to fix
As suggested in the "Jumbled Text" issue, restarting the client helps.
