Why these glitches?

I see display problems on Sheet Layers all the time. They are definitely bugs and not hardware issues as I am running an iMac Pro.......

It's so common - danger is it becomes the norm and doesn't get flagged enough.

 

Really not what you would expect from professional software - VWX 2019 so relatively mature software now too.

Yup, I've been getting this too.  It seems as though Vectorworks has recently become infested with bugs. Really not what you'd expect when paying the amount we are.

Me too.  Hard to replicate.  Generally fixed by a re-start.  Not awesome.

This could still be an issue with the eGPU and its data throughput. I have seen similar behaviour on a dedicated GPU with other CAD software as well with relatively modest size drawings and getting a better GPU with more VRAM and especially data throughput rate solved the issue. The "devil was in the details" in those cases, i.e. the more details/small items there were the more likely the issue was to happen, even if the total drawing was not that big.

 

There are definitely display bugs as well, but in your case the use of an eGPU might be a factor to consider. Do you have an opportunity to try a computer with a good dedicated graphics card to see how it behaves there? That way you might be able to tell if it could be the eGPU or not.

I’m afraid it occurs just as often when I am not using an egpu (MacBook Pro). 

 

I just mentioned the egpu to point out I am using VWX with a decent GPU

The graphic's 'glitches do seem to be getting worse, though many have been around for as long as I can remember; but this particular glitch, I find , only occurs once you've opened a second document and performed a few graphic's orientated actions in it.

Really?  All going ok on this lovely Bank Holiday Monday though I would much rather be enjoying the sun that working.

 

Then I start getting this.  Keynote legends disappearing and only re-appearing briefly when I force a screen refresh (command 4).  Luckily a restart fixed it but honestly - is this software tested for bugs?

@Andrew Davies, I'm experiencing the same phenomenon with a 2013 Mac Pro with 64GB RAM and the D700 Graphics.. so, not a super current machine, but no slouch either... Maybe it's just a display bug, but justifiably, still makes one nervous about file corruption/ data loss..

I'm getting a lot of screen glitches, as well. Lot's of crashes, and it is running extremely slow. Running on 1080ti GPU, new laptop.

Any comment back from Nemetschek?  This is so common.  Happening again now.  Different file, different project

Do you have a file showing this behaviour that you could share? It would be interesting to see if it happens on my system(s) as well as I do have some fairly loaded files and am not experiencing this issue.

 

If it hadn't been for the one nVidia card mentioned I would think it might have to do with the graphics card being Radeon cards, as there used to be some display issues with those cards that were not (as much) happening with nVidia cards due to some driver related things.

 

Nonetheless I would still be inclined to think it is a RAM/VRAM issue as the behaviour is the same as I was having when the amount of RAM/VRAM turned out to be too low to keep up with the display requirements and after moving to a new computer with better RAM and VRAM/GPU these particular issues disappeared. I was still having lag issues but that was a VW issue. It could be that VW might be using way more memory than it needs or is having some memory leak that cause you to run into having to low memory resources for proper display. The fact that the issue disappears after a restart does, at least to me, point into that direction of RAM/VRAM issue in combination with VW.

 

If other applications are not showing similar behaviour then VW is certainly a factor, whether it is because of its hardware requirements or a bug does not really make much difference for someone with a fairly new computer and decent graphics card as both things are something that Vectorworks should solve, either by better optimizing resource usage or fixing a bus if there is one. This thing is definitely not good for ones workflow.

@Andrew Davieswhat are your VW Preference settings under Display for Navigation Graphics? If these are set to Best Performance try Changing them to best Compatability to see if that changes anything for you.
