Font Becomes Too Small, Unreadable or Distorted After Applying 10.1.2.2 (or 9.0.

Applies to:

Oracle Forms - Version: 10.1.2.2.0
This problem can occur on any platform.
Also Forms Services 9.0.4.3

Symptoms

After applying Oracle Application Server / Developer Suite 10gR2 Patchset 2 (10.1.2.2) i.e. Patch 4960210 font appearance can become distorted or minuscule.

For example the text on buttons can now be so tiny that it is no longer readable. On some items the font can become broader and coarse.

A similar issue (possibly different font appearance distortions though) occurs after applying Patchset 3 ( 9.0.4.3) on OAS 10g i.e. Patch 4948949 or on ODS 10g i.e. Patch 4948955.

Changes

- OAS / ODS 10gR2 Patchset 2 ( 101.2.2) Patch 4960210 has been applied on 10.1.2.0.2 ( or Patchset 3 (9.0.4.3) on a 10g install )
- The forms are using REAL UNIT = PIXEL

Cause
