Some testers needed! I can not reproduce the BitBlt bug and I would like to get this right, so that surface pattern paints use the correct form dimension. Prefered test setup: a (fresh) pharo image load bleeding edge from Bloc (because with bloc the whole (morphic) world is drawn with athens). change to watery theme ( because it makes some heavy use of form fills) verify that vertical scrollbars have this artifact (blank lines). load the attached code (this code reverts igors change for the 1 pixel extra height. please report back what platform windows/linux/mac 32/64 bit what pharo vm and image version. For me Windows 7 32 bit Win32 built on Apr 9 2015 21:05:04 Compiler: 4.6.2 Latest update: #50039 -> no segfault thanks in advance 2015-03-13 21:22 GMT+01:00 stepharo <stepharo@free.fr>:

Because with the fix in 13236, it is not (easily) possible to make a repeating (vertical) pattern paint with 1 pixel height: 14813 <https://pharo.fogbugz.com/default.asp?14813> Wrong size for Athens surface pattern paint from a Form
