Prevent out-of-bounds access.

Browse Source 
This fixes the issue when assembly view is scrolled to the bottom of the
screen and display scale is reduced by the user. In such case clipper will
report DisplayStart to be at the end element, which would cause out-of-bounds
access to the m_asm array.

Clipper self-fixes this in the next frame, so this workaround is enough.
