What do you think?
Yes, it is worth to try.
BTW it would be good to know do we really need passiveDCList, which
is populated on "WM_AWT_RELEASEDC" and immediately cleaned.
Yes, we still need passiveDCList. A DC can be moved to the passive list
by DisposeThreadGraphicsInfo function in GDIWindowSurfaceData.cpp. This
is called not on the toolkit thread, so we have to defer releasing the
DC in this case.
However, I agree, we can simplify releasing DCs when on the toolkit
thread by skipping the passive list. Yet having two different approaches
could be error prone.
