Visual glitch in live backplot

I'm experiencing a visual glitch that often happens within the preview window after clearing the backplot

The Preview looks fine when a file is loaded
Preview glitches after clearing the live backplot (Some times)
- Preview has missing parts/skewed lines
- Preview has flashing lines
- Back plot doesn't update when you move the machine
- Tool cone rendered incorrectly
- Doesn't appear to be file specific

Zooming in a certain amount will clear the issue and things will render fine until you clear the backplot.

This doesn't appear to affect the job operation, you can go ahead and run things just fine.

The severity of the glitching varies. Sometimes it's minor, sometimes the whole preview disappears.

Running an older version of LinuxCNC/Axis: version 2.7.4. My google-fu was not strong enough to find other issues similar to this.

Any input appreciated, thank you!

Thanks for the heads up tommylight, took me a minute to get that right!

Seems like a refreshing glitch or OpenGL, what graphic card?

It is an intel Atom D510 with GMA 3150 integrated graphics.
