AutoCAD Web App super glitchy on Chromebooks - choppy, jumps around, does not work right

[bparksQD7EX]

I teach CAD and my classes are running the AutoCAD Web App on Chromebooks this year with remote/hybrid formats.  But it has been a HORRIBLE experience.  Every one of the students' 64-bit Chromebooks are super glitchy in the drawing screen.  It is not glitchy in the left-hand menus where the toolbars are.  But the drawing screen where the lines go is super glitchy, jumping around, making it almost non-usable.

Does anyone have a fix for this?  I would like to continue to run AutoCAD for my students, and since they are remote/hybrid, I need a platform to run on Lenovo Chromebooks (64-bit).    But I will have to discontinue using Acad if it stays this poor of quality.  Any feedback is much appreciated!

'glitchy" means what to those reading this post?

if you want to look for alternatives, the app store for those CBs is the only option you've got: try before you commit.

Hello @bparksQD7EX 

Welcome to the Autodes Web App Forum.

Having a look at post "Will this become available for Lenovo Chromebooks" I understand it similar than yours. Summarizing this and the linked topic, I understand the situation as follows: 

Currently supported for AutoCAD Web App are only 64 bit browsers (source AutoCAD Web App FAQ😞

The AutoCAD web app is supported by 64-bit Google Chrome, 64-bit Mozilla Firefox, and 64-bit new Microsoft Edge (Chromium based) on Windows or Mac. For the best performance, it is recommended to use the latest version.Since this product runs entirely on the web, the system requirements are minimal. It is recommended that you have at least 2GB of RAM.

64 bit browsers on Levono Chromebooks (source post "Will this become available for Lenovo Chromebooks")

• "AutoCAD web requires a 64bit Chrome browser for ideal performance."
• "Lenovo is posting that none of their chromebooks run 64 bit browsers."  If this is still the case then the Chromebooks and their browsers unfortunately do not fulfill the system requirements for AutoCAD Web App.

If 64 bit browsers become available, choose the browsers mentioned in the system requirements above. 

Feedback about the situation

I recommend to post your situation and mentioned numbers on the topic "Give us feedback on AutoCAD web".

Thank you for the reply, @pendean 

Glitchy means when you drag the cursor, it jumps, lags, is choppy, not a smooth travel of the cursor, esp. with using the commands (e.g. something as simple as drawing a line).  Thank you for recommending the app store; I hadn't thought about that.  I was hoping to be able to use an Acad product before looking for other apps that do drafting/design.

Thank you for the reply,  @Thomas_Stuehle 

Yes, I did read over the other discussion threads.  The Lenovo chromebook I have says in the system settings that it is 64-bit.  I don't remember on the RAM; I will look into it.  But with the 64-bit processor, I assumed Acad Web App would work. 

Any tips on changing the settings (e.g. limiting the model space, different raster settings, etc.) so it computes faster?

>>>...Every one of the students' 64-bit Chromebooks are super glitchy in the drawing screen...<<<
Does that mean you are NOT running on the same device to repeat the problem, but are relying on your students for feedback?
Or do you have the same exact device but for you all works just fine?

Which Lenovo Chromebook make/model/spec number did your district provide for everyone?
Which version of ChromeOS are the students running?

I have a CB, as does the rest of the students.  On all of our units, the cursor is glitchy/choppy/jumpy/laggy in the drawing window (not over the toolbars).  The cursor operates smoothly over the other areas (toolbars, Chrome menus, etc.).  It is just glitchy in the drawing area, so much so that you really cannot drag the cursor and click to draw a line without waiting 5 sec. each time waiting for the cursor to catch up.

From, IT, he said they all have the following specs:

Lenovo N23 - Specs

• CPU. Intel Celeron N3060 251.
• GPU. Intel HD Graphics 400 (Braswell) 263.
• Display. 11.6”, HD (1366 x 768), IPS.
• HDD/SSD. 32GB eMMC.
• RAM. 4GB
  
  
• I checked my machine, and under the "About Chrome OS"  it said version 84.0.4147.136 (Official Build) (64-bit).

But yes, we all are experiencing these issues in the drawing area only.

Thanks for the additional details, that should help @Thomas_Stuehle dig a little deeper for you all.

Web customer reviews are mixed on that unit from what I can tell.

Hello @bparksQD7EX 

Thank you for further details and @pendean thank you for following up.

I used all information to request more details about the situation internally. I will update you directly when I have new information.

Until then: Does it make a difference on your side when your Browser is in full screen mode or not?

Thank you for the reply and for digging into the issue more.  

I just logged on and tried it on the Chrome browser in both full screen (maximize) mode and non-full screen (restore down) mode.  It is still glitchy in both screen modes.  So, unfortunately, there is no difference that I can tell between the two.

@Thomas_Stuehle Any word yet on the chromebook issues?  Just wanting to follow up.  Please let me know.  Thanks.

Hello @bparksQD7EX 

Thanks for your follow up.

I don’t think we have a chance here with the Chromebooks - maybe only with a virtual environment on the chromebooks, if a 64 bit browser can be installed in that virtual environment. No 100% sure if this is possible, but that could be a way forward to stay with the hardware.

Unfortunately we can’t support 32 bit Chrome browser. The 64 bit processor is not enough.I found this post in the Google forums: https://support.google.com/chromebook/thread/11589775?hl=en

@Thomas_Stuehle 

Thank you for the update.  So from what you are saying, the Chrome OS cannot run the AutoCAD web app, even if it is a 64 bit OS, because it is a Chrome OS?  Just making sure I read that correctly before I scrap using Autocad and switch to a different CAD platform.

On a personal note - I've used AutoCAD for 25+ years, both in industry and in the classroom.  I know for us, this will severely affect students learning/using the AutoCAD platform in this pandemic.  This may also have longer-term repercussions on using AD's products.  I know you personally cannot fix it, but I wanted to at least mention it since it is coming from a user of AutoCAD and teaching AutoCAD to hundreds of students a year.  I was hopeful that the web app would be at least a very basic platform for them to learn the basics of the fuller version.  Them not being able to use the Acad web app on ChromeOS will lose a lot of market buy-in, because that's what most public schools are primarily running.  Just thinking out loud here and wanted to share that.  

Thanks again for looking deeper into this issue more.  I appreciate it.

Hello @bparksQD7EX 

sorry to hear that and sorry for a possible misleading formulation. 

The root are non 64 bit browsers - if non 64 bit browsers are used, the AutoCAD Web App might show unexpected behavior.

See: "Supported Browsers and System Requirements"

"The AutoCAD web app is supported by 64-bit Google Chrome, 64-bit Mozilla Firefox, and 64-bit new Microsoft Edge (Chromium based) on Windows or Mac."

Hi @bparksQD7EX 

additionally I got the information that it works in general with 32bit browsers - it is just a bit slower. This is most probably exactly the behavior you experience.
