Bug#887437: x11-common: When I attempt any resolution over 1920x1200 text is unreadable

[Bengt Hammarlin <bength@hammarlin.com>]

Package: x11-common
Version: 1:7.7+19
Severity: important

Dear Maintainer,

Trying to use a 4K monitor gets garbled text etc.

Tried 3 different graphics cards that handles over 1920x1200 all with valid
drivers.
Any attempts at a resolution over 1920x1200 (such as 2560x1440 or 3840x2180)
garbles text and other finer details. The instant the resolution is below it is
chrystal clear.
