--- Comment #11 from bluescreen_aven...@verizon.net --- I tried to add the lines qCWarning(KWIN_FB) << "Alpha Length: " << m_alpha.length; qCWarning(KWIN_FB) << "Alpha Offset: " << m_alpha.offset; qCWarning(KWIN_FB) << "Red Length: " << m_red.length; qCWarning(KWIN_FB) << "Red Offset: " << m_red.offset; qCWarning(KWIN_FB) << "Green Length: " << m_green.length; qCWarning(KWIN_FB) << "Green Offset: " << m_green.offset; qCWarning(KWIN_FB) << "Blue Length: " << m_blue.length; qCWarning(KWIN_FB) << "Blue Offset: " << m_blue.offset; in FramebufferBackend::queryScreenInfo() to see if a difference there could be the cause of the late: QPainter::begin Paint device returned engine == 0, type 3 which occurs sometime after Xwayland starts, which that line does not appear on my physical box when using the framebuffer at least. (if that even is related to the issue) and they all seem to be correct for what FramebufferBackend::imageFormat() tries to match for in QEMU... Alpha Length:0 Alpha Offset:0 Red Length: 8 Red Offset: 16 Green Length: 8 Green Offset: 8 Blue Length: 8 Blue Offset :0 -- You are receiving this mail because: You are watching all bug changes.
