Right click menu issues

[YannickEnrico]

Hey there. 

I have, for a while now, had issues with right click. 

If I right click on an item/feature in an assembly, drawing or part it sometimes instantly chooses repeat (last command).

It doesn't instantly choose anything if I right click on the "paper" or the world where there are no items (I.e. parts, part lists, and what not). 

If I click and hold right click, it seems like it doesn't do it. 

I can't reproduce this behavior other places than Inventor. 

I'm running 2018, fully updated. I don't recall when this started, although I can certainly say I didn't experience it in 2017, but it has been an issue for a while now. 

Anyone knows what's up, or what I can do to test my hardware properly?

Yannick

Hi Mike,

Qt is a common UI framework. Quite a few Autodesk and non-Autodesk programs leverage it. I think the safest choice is the following. If they don't work, simply revert back. No harm done.

1. "QT_AUTO_SCREEN_SCALE_FACTOR" as 0.
2. "QT_SCALE_FACTOR" as 1. 

There is no need to reboot. Simply close Inventor, add the variables, and restart Inventor. After that, run AutoCAD (if you have it) and see if there is anything wrong. It should just work. Or, your issue isn't related to Qt.

Many thanks!

Johnson after getting more complaints I've dug deeper and experiencing it myself now and on most computers.  

So some interesting tid bits.  We are nearly 100% Nvidia GeForce cards as they've always treated us well and all have a pretty healthy amount of Memory

• Updating drivers helps sometimes.
• As the session open time increases the right click slows down.  It will start with instantaneous right click menus but as the session continues it slows down to 5,10,15 seconds for a right click or to get something to highlight in the browser.
• Restarting Inventor it comes right back to full speed.
• Right click issue only happens when a component is selected.  If you right click on the empty canvas away from the parts right click is instantaneously.
• All the PCs and laptops do have integrated cards and Nvidia cards.  With most of them are set to use the Nvidia processor for Inventor and also set the default process for all apps as the Nvidia processor.  We are setting that in the Nvidia Control Panel
• So when watching the video cards in Inventor and we orbit a model both video cards are ramping up about similar percentages.  In my mind it should be nearly all Nvidia.
• So I'm thinking the issue is how Windows is directing the Video Traffic.
• Yesterday on my PC I was working in IV and also running Microsoft OneNote on the other screen and when the right click started bogging down in Inventor my cursor was very slow to react in OneNote as well.
• We are all running a 2nd monitor ( very few to none are 4K) and we found no difference of we only use a single screen.  Was thinking if windows was trying to scale 1 monitor vs. the other.  Again no success other than to restart IV.
• The linked screencast is 1 we put together to show the right click lag: https://autode.sk/3AIpOXM 
• This 2nd video showing how both video cards are getting hit when orbiting the model.  This is via a 3D connexion space navigator:  https://autode.sk/39Aa3WJ 
• 3rd Screencast is when Steve was trying to edit a part within an assembly and both video cards were showing next to 0 usage, but CPU went to 100% and was extremely slow to react which might contradict our theory on video issues. https://www.screencast.com/t/veCSOmBtbt 
• Open to trying anything.

Thanks much!

 Hi Mike,

Many thanks for documenting the behaviors! It looks like something is wrong in Inventor. I will need to work with the project team and see if this is a known issue.

Thanks again!

Hi Mike,

I have contacted the project team and got some interesting information. So far we suspect it could be related to integrated graphics card. For performance purposes, some PC may assign certain tasks to integrated graphics card and some more heavy lifting tasks to the dedicated graphics card. The switching between cards actually prove to make things worse.

Try going to Nvidia Control Panel -> make sure Inventor.exe run on the dedicated card. If this does not work, it may require you to change the setting in PC BIOS to force the system to use the dedicated card.

Many thanks!

Thanks Johnson.  Yep our Nvidia control panel is set to use Nvidia processors for Inventor.exe.

We'll see what we can tweak in the Bios on the worst machine.

Will follow up with our findings.

Another update on things we've tried with little success.

This screen cast is a synopsis of things we've tried in regards to Video cards and disabling them.

This screencast is from Steve which is really baffling to us.  Short of it is that IV seems to use 100% of a core anytime you click on something in some IAMs.  Secondly and the most baffling is that say you have 3 levels of structure for a machine.  If you have all 3 IAMS open and you pick on the same part and right click on it in the 3 different iams, the right click time varies greatly depending on the IAM, and the largest iam typically is not the slowest.

Thanks Again!

@johnsonshiue and crew - hang loose on spending much time on it.  We think the iProperty Wizard Add-In may be causing it.  Or some remnants of a beta version of the iPropWiz we tested that are causing it.  We'll do some more testing and follow up.

Hi Mike,

Many thanks for sharing the update! We are still clueless at the moment besides what I have conveyed so far. Please let us know what you find out.

Thanks again!

Hi Mike,

While iPropWiz may be the reason of the slow performance, there is another issue discovered recently related to "My Home" page. To check if this is the case, please help try unchecking "Show My Home on startup" and restarting Inventor to see the difference.

When the slow performance happens, some experiments to help locate the cause:

1. Left click a part and see whether it is slow.
2. After left click a part and select it, right click the same part to see the speed at which the menu pops up.
3. Left/Right click the part on the Model browser tree and check the performance.

Thanks

@HelmesHe - Thanks for the feedback.            @steveh3 

At this point we believe it is the Document Browser built into the iProperty Wizard which we diagnosed with the help of the iProperty Wizard team.  If we turn that off there's no regression in performance as the session goes on.  More testing to prove this.  Everyone in our company should have that turned off by Morning, so we'll see if it helps everyone.  If it does not we'll try the "My Home Page" you suggested.  I"ll be in touch.

Regards!
