Adding a few people and components who might know more.

Do we know if Ericom Access uses WebRTC? Searching for "WebRTC" on their website yields no hits. http://www.ericom.com/access-now/html5-rdp-client/
,

How do we reliably check? We have their demo installed, but I can't find any mention of WebRTC.
,
Aug 31 2017
While running their app in Chrome, go to chrome://webrtc-internals and see if you see a PeerConnection running. If not, they are not using WebRTC. (-RVG, which I added by mistake before.)
,
Aug 31 2017
Nothing in chrome://webrtc-internals while it's running.

Ok, I think that would mean that the WebRTC renderer is not used. +niklase to confirm.

Hi guys, i asked ericom about WebRTC and here is the answer: Hello, AccessNow does not offer support for WebRTC and implementing it is not considered in the near future.

vkhabarov, It isn't clear from this ticket if we have tried to reproduce on other Chromebook types (besides elm or hana)? Note: Since this apparantly did not occur in R52, our initial suspicion is that this might be a regression introduced by the IMG DDK update from 1.7 -> 1.8 which rolled out in R59. If you can reproduce easily, can you try on older R58 elm image (anything before 9692.0.0)?
,

I can reproduce the issue easily, and we have multiple devices in our company. But I don't know what to test. I can only reproduce it on acer R13 models.
,
Oct 23 2017
@djkurtz I couldn't repro the issue on other devices. I just tried 9334.72.0 on Hana - still reproduces.
,
Oct 24 2017
Do we have any instructions for how to reproduce the issue? Is there a demo account or similar?
,
Oct 24 2017
@bhthompson We installed demo version of this software on our test server and used it, I could share credentials to it. Repro instructions are kind of vague, I just use Ericom own server config window and quickly switch between tabs, until I see artifacts (or won't see any)
,
Oct 31 2017
Could we share the credentials with the Imagination folks whom can help with such GPU issues? We can share them offline assuming they should not be posted to a public bug.
,
Nov 2 2017
Sent test credentials to bhthompson

Hi Guys, Could you give a status update about this issue? With kind regards, Thomas van Latum g-company
,
Nov 17 2017
Hi Bernie, Are there any news from Imagination? Thanks!
,
Nov 18 2017
Imagination folks (Afar?) can you comment on debug status here? IIRC this was reproducible with the credentials.

Hi Guys, Could you update us about this issue? Regards

Hi All, I'm part of the Imagination support team has been looking at this issue. Firstly, apologies for the delay while we've been investigating this. The info we've found so far is pointing to an app synchronisation bug. We've taken a graphics trace of the OpenGL calls that are being used when running this app on the Chromebook and by playing the trace back on a PC (using a non-Imagination graphics stack) this issue is still reproducible. This leads us to believe that the issue is outside our GPU driver. We're working to provide more details over the next few days so this can be investigated further. Many thanks, Ian

Dec 12 2017
Ian, are you able to reproduce on any other Chromebooks without Imagination graphics?
,
Dec 12 2017
Oh, I just saw comment #14, it was noted that this issue does *not* reproduce on any other Chromebooks. Also, from comment #1, the original report said that this issue was not reproducible on Imagination chromebooks on M52, but appeared in M58. One next step would be to double check that this issue did indeed begin with the introduction of 1.8 driver. Also, can you take an API trace with 1.7 and check whether it is the App or driver behaving differently between the two different driver versions.
,

Hi All, Who needs to to double check if this issue began with the introduction of 1.8 driver? Regards,

Hi, Apologies for the delay. Our investigations are continuing although were delayed by the holiday period. I've been advised that the server credentials (IP, Username and Password) we were using for testing this app no longer work as of this week. Is it possible for someone to provide us with working credentials so we can continue looking at this? Thanks, Ian
,
Jan 15 2018
Hi Guys, We need a fix for this as soon as possible because we need to update our devices to fix the Meltdown bug. Regards, Thomas
,
Jan 15 2018
@ian, I've sent you an email with Ip, username & password of the test server.
,
Jan 25 2018
djkurtz@, is there any update to this issue? Please let us know if anything else is needed from customers.
,

,
Jan 26 2018
@All, Please update this case our customer needs to roll out the chrome devices.
,
Feb 6 2018
@imagination: do you have necessary access for testing? Do we need buganizer bug for better tracking/communication? Customer is constantly asking for news and updates
,
Feb 7 2018
All, I'm pleased to say our investigations have finally led us to a fix for this problem. We will provide this patch on Gerrit ASAP and post back here when we know which ChromeOS version will contain the fix. Thanks for your patience, Ian

Fix landed in R66-10386.0.0. Who can double-check that the fix works? Then we can backport to R65 and maybe R64.

Feb 13 2018
If someone can verify this fixed it on an R66 official build (canary channel today, dev channel later this week), we can pick this back to R65 (currently beta).
,
Feb 16 2018
Hi, Could someone explain to me how to update a chromebook to R66? We would like to test to see if the issue is fixed. Regards, Thomas
,
Feb 17 2018
I believe we are still serving R65 on dev channel, so one way would be to switch to canary channel (these instructions look correct: https://www.howtogeek.com/308602/how-to-switch-to-or-leave-the-canary-channel-on-your-chromebook/)
,
Feb 19 2018
Hi, I've switched one of our chromebooks to canary channel. Cannot reproduce the graphical glitch anymore so i think the problem is solved. Many thanks!!!
