Tenortex, I know I'm late here by about a month but take a look at your SystemUI.apk in "A". It has a directory that the SystemUI.apk from version 10 does not have: "raw". Within that directory are the combined images for the digital battery meter in the bar. I think that is the source of "A" freezing units. Nick's solution for Touch of ICS was to completely replace each battery meter image with a digital meter PNG, identical to what you did for the battery icon with the white border.
The only reason I found this out is that I tore open the .apk files to attempt to solve the minor annoyances I mentioned back in January, except for the center clock. I'm used to that one now.
