  • sometimes geometry draws as if in xray

Object glichted sometimes when switching between normal view and quad views in the view port if viewport aa set to 32

Can confirm.

Caused by rBc476c36e4008: Workbench Simplification Refactor

Might need a kick to wpd->view_updated = true (similar to rB133bf05b184b, rBa6dd22d4311c, rBed44bb902d6b, rB02f7a6b2bdea ...)

(but of course, we shouldnt be messing with RV3D_VIEWLOCK_INIT like that...)

Seems like 2 tickets in one. The glitch has been reported already so I assume this ticket is about the tagging...

I wasn't able to reproduce the quad view tagging issue on latest build. @Philipp Oeser (lichtwerk) do think this is a platform specific problem? If so I can try building this configuration. Just wanna check before spending much time building the configuration.

Tested myself on Linux AMD Vega64 and Windows Intel

Mind sharing which the other report is?

Cannot tell (I only have access to this one machine...) And I still have it on

@Philipp Oeser (lichtwerk), seem that other tickets are for Intel and NVidia. perhaps we just split these tickets.

Philipp Oeser (lichtwerk) added a comment.May 8 2020, 11:12 AM

But other tickets are specifically about quadview? Which other reports are these? [I have no other glitches]

Jeroen Bakker (jbakker) added a comment.May 8 2020, 11:58 AM

I was able to reproduce this issue but only on Windows. I did reproduce it on Intel and multiple AMD cards.

Clément Foucault (fclem) added a comment.May 11 2020, 3:52 PM

I was able to reproduce on Nvidia GTX960 + Windows.
