arcean, two observations:
1. In task manager view, when quickly changing screen orientation (by moving the slider) back and forth, sometimes orientation is not properly updated. I.e. desktop is in portrait but going to task manager view takes you to landscape and then back to portrait when returning to desktop. I know it`s not much, but it`s random: I can`t figure out reproducible way to trigger it.
2. In task manager view, I had frozen app thumbnail once. I`m using thp "thumb_desaturation=1" and "taskswitcher=2". Single sms conversation window upon touching "X" mark turned grayish (like it should) but didn`t close shortly after (or it actually was closed by the system properly but task manager was still displaying it).

I don`t know if it`s 2.2.152.2-1 specific but I only experienced pt.1 and pt.2 shortly after it`s installation and never before.
