[Bug 1573470] Re: BQ M10 tablet. Libreoffice Impress display wrong colors
Alright, thanks. I just dont see the point of shipping impress preinstalled if it cannot be used for presentations.

[Bug 1573470] Re: BQ M10 tablet. Libreoffice Impress display wrong colors
Minor success. I've made a test available that you can use to replicate the bug using a desktop: https://git.launchpad.net/~xmir-team/xorg-server/+git/xmir/commit/?id=637f0971b191c9fbdc459f3fdb7ba5bc479b84be So this shows the problem is triggered by the priority order of supported pixel formats the Android platform returns. Mir's Android platform is returning the correct values in the correct order, but it's different to desktops, and that's enough to trigger this bug in Xorg. It remains to be seen if the problem is an issue in Xorg that's always been there, or just something that Xmir is failing to initialize correctly. Mir's Android graphics platform unfortunately does not support the same pixel formats as desktop that would avoid this bug. However adding ShmBuffer support to the Android platform would allow it to support all such pixel formats (and solve other bugs like the corruption issues). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573470 Title: BQ M10 tablet.

It's possible that a newer Mesa has fixed this problem already. Because a similar setup (LLVMpipe software rendering in Xmir) on desktop has no discolouration: Working: xenial with Mesa 11.2.0 (desktop) Broken: vivid with Mesa 10.5.9 (Ubuntu Phone stable channel) P.S.

[Bug 1573470] Re: BQ M10 tablet. Libreoffice Impress display wrong colors
xwininfo/xdpyinfo seems to confirm the red and blue channels are reversed for GLX windows: visual: visual id:0xb4 class:TrueColor depth:24 planes available colormap entries:256 per subfield red, green, blue masks:0xff, 0xff00, 0xff significant bits in color specification:8 bits versus non-GLX windows: visual: visual id:0x28 class:TrueColor depth:24 planes available colormap entries:256 per subfield red, green, blue masks:0xff, 0xff00, 0xff significant bits in color specification:8 bits However the problem is not as simple as changing a pixel format. Xmir is running in rooted mode, so we only get to choose one visual for the whole display at start-up. So we need to find a way to force GLX to use the correct visual, or to force XComposite to mix the colours correctly. Because it's really out of Mir's control... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573470 Title: BQ M10 tablet.

This might be a GLX problem.

[Bug 1573470] Re: BQ M10 tablet. Libreoffice Impress display wrong colors
I've done some investigating. With a Unity8 desktop system running on amd64 using Vivid plus the overlay PPA, the colors stay correct in Slide Show mode. So at this point, it's most definitely an issue specific to armhf and most likely an issue either in Mir of Xmir where the buffers get switched around somehow. We will need one of those guys to look at this as that is a little out of my realm of knowledge:) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573470 Title: BQ M10 tablet.

Yes the colors do not match between editing and presentation modes, in edit mode they are as displayed on desktop. ** Changed in: canonical-devices-system-image Importance: Undecided => High ** Changed in: canonical-devices-system-image Status: New => Confirmed ** Changed in: canonical-devices-system-image Assignee: (unassigned) => Stephen M.
