http://bugs.winehq.org/show_bug.cgi?id=58921 --- Comment #13 from Wehrwolfmann <wehrwolfmann@gmail.com> --- Follow-up to comment #12: a local experiment points at where the fix goes. When the presenter sees a target window that has WS_EX_LAYERED but no layered attributes (GetLayeredWindowAttributes fails on it) and hands the frame to UpdateLayeredWindow with ULW_ALPHA instead of drawing into GetDCEx, variant B turns red on 11.18 with the staging patchset, while A and C stay red as before. Deciding this once, when the target is bound to the window, is enough; nothing has to be polled per frame. I am not posting a patch, only the observation, so whoever maintains the patchset can do it their way. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
