http://bugs.winehq.org/show_bug.cgi?id=58921 --- Comment #16 from Wehrwolfmann <wehrwolfmann@gmail.com> --- I ran both layouts on the fork's d2d1-dcomp-11.19: 64-bit, fresh prefix, win10, Xvfb, llvmpipe, 20 screen samples per run. Comment 14: WS_POPUP top-level, client == window, ex-style 0x00280000, no layered attributes, swapchain on a child visual, root visual empty. At 882a4d488d4 (parent of 696859799d6) nothing is shown, the X window is unmapped. At cb9ab98273d and c3c3d74a571 it is shown, 5 runs of 5, and the log has the UpdateLayeredWindow line. Comment 15: process 1 owns a WS_POPUP top-level with WS_EX_LAYERED only and repaints it blue with UpdateLayeredWindow every 200 ms; process 2 creates a WS_CHILD in it and composes red. Child ex-styles 0x00280024, 0x00280000, 0x00200000, 0x00200020, swapchain on the root or on a child visual. At c3c3d74a571 it depends on where the child sits. With one plain child window between it and the layered top-level all eight are red (blue at cb9ab98273d). Created directly in the layered top-level all eight stay blue; when that child covers the whole window, exactly one pixel is red, the top-left one. The probe from comment 12 is red in A, B and C at both commits, by the path the fork had before (framed window, swapchain on the root visual). Razer Axon paints fully at c3c3d74a571. Nothing here was run on Windows. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
