Hi all,
I’ve put together a yocto build for the BBB which uses weston+wayland driven by the sgx kernel modules.
I’m using this as a wrapper around libEGL: https://github.com/schnitzeltony/ti-omap3-sgx-wayland-wsegl/tree/drm-gbmAnd I’m using some bit bake hackery based on: http://gitorious.org/schnitzeltony-oe-meta/meta-gumstix-community
I’m running ti’s 3.12 staging kernel with the 5.01.01.01 GFX release.
It all seems to work, but I’m seeing some strange display wrapping on the monitor I’ve got hooked up. Essentially, “sometimes” the display rotates/shifts left by a few pixels. It’s always the same amount, always the same shift direction, and either displays properly or has this defect. It shows up and goes away as I change what is rendered on the screen (typing, moving windows) with no apparent pattern.
Here’s a photo showing the slight wrap-around that I’m describing here. Look at the right edge of the screen: http://i.imgur.com/8S7H9uV.jpg
I’m wondering if this is a known HDMI issue? Or a libgles-omap3 issue that needs to be hacked around? Or something else?
