New subject: [PATCH 2/3] riched20: Don't assume that TxDraw preserves the device context's brush selection.

From: Jinoh Kang jinoh.kang.kr@gmail.com

Today, RichEditWndProc_common assumes that ITextServices::TxDraw preserves the brush selection of the given device context. However, this invariant may be broken by misbehaving embedded OLE objects in the text document.

Fix this by not assuming that the return value of the second SelectObject() call equals the brush passed to the first SelectObject() call in RichEditWndProc_common's WM_PAINT / WM_PRINTCLIENT case. --- dlls/riched20/txthost.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-)
