Finally I got some time to test that patch too. I checked out branch
`debian-unstable` from the Debian packaging Git repository [1] (based on
release 2.19.0)
commit 8ab872522ae0891b8fb52fbb31db52d581c3efa3

Upload to unstable
and applied the following patch on top of it.

intel: Throttle harder
Limited testing shows that the glyph corruption is gone. Unfortunately
performance seems to be slower too. That means for example maximizing a
window it does not happen instantly and I can see how it is redrawn. So
basically the same behavior with `"DebugWait" "true"`, if I remember
correctly.
