    <p>In Voxel.js, a Three.js based project that I work on, we recently started seeing a weird rendering that shows up on Macbook Airs (Intel HD Graphics 3000) but it doesn't show up on other Macbooks like those with GeForce 320Ms. </p> <p>Here are 4 screenshots from the Canary WebGL Profiler showing how the line appears <a href="https://imgur.com/a/2eRhO#0" rel="noreferrer">http://imgur.com/a/2eRhO#0</a></p> <p>The line itself is the same color as the three.js renderer fill color so it isn't visible until there are non-fill colored things being drawn to the canvas</p> <p>To try and reproduce the glitch, here is a demo: <a href="http://maxogden.github.io/voxel-hello-world" rel="noreferrer">http://maxogden.github.io/voxel-hello-world</a> just look around a bit until the lines show up</p> <p>Here is a video of the glitches showing up during gameplay <a href="http://www.youtube.com/watch?v=KfR8tJ36KuY" rel="noreferrer">http://www.youtube.com/watch?v=KfR8tJ36KuY</a></p> <p>And another screenshot where the fill color is set to pink <a href="https://i.imgur.com/Ww6nMOA.png" rel="noreferrer">http://i.imgur.com/Ww6nMOA.png</a></p> <p>The code that I believe introduced this glitch is here: <a href="https://github.com/shama/voxel-texture/blob/master/index.js" rel="noreferrer">https://github.com/shama/voxel-texture/blob/master/index.js</a></p> <p>We used to use many .png textures, one for each texture, but now we use composite texture atlases that are packed and generated on the fly, e.g. <a href="https://imgur.com/qgSYSNf" rel="noreferrer">http://imgur.com/qgSYSNf</a></p> <p>Has anyone seen this behavior before? Any ideas on how I could track down the root cause?</p>

    1. COI would say it looks like a problem with buffering... Can you turn hardware acceleration off on the Macbook air? Also are there any simple examples that come with Three that exhibit the problem?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
