Hi @katsick, Unfortunately due to how old these devices are & given that they are no longer supported by the manufacturer, we do not have plans to try and create a workaround this driver bug at the moment. Matt

Thanks for the information! We got access to an old machine with an Intel HD 4000, and can confirm the issue. At the moment though, because these chips are so old and no longer supported by the manufacturer, we do not plan on patching for this right now. We can try and investigate installing a workaround for this driver bug in 4.30, especially if more people start running into this. Edit: At the moment we do not have plans to workaround this driver bug due to how old these devices are.

@FC_Basson unfortunately it looks like some of these old machines were recycled, but I was able to get access to a machine with an intel hd 4400 & am trying to reproduce. To confirm, the issue can be see with https://developers.arcgis.com/javascript/latest/sample-code/intro-graphics/? Can it also be seen with https://developers.arcgis.com/javascript/latest/sample-code/layers-featurelayer/?

@FC_Basson that processor actually came out in 2012 so it's probably 11-12 years old 😅. That said, I know we have an old Intel hd 3000/4000 device in storage somewhere as I remember installing some workarounds related to those in the past.

@FC_Basson, we're currently trying to get ahold of a device with similar specs.

For those who are experiencing the flickering, do you still see here? with: https://bsvensson.github.io/various-tests/compare-webmaps/webmap.html?webmap=87e7f204fd1f4595ada62603359ec40c&api=https://jsdev.arcgis.com/next/

Also we do have a workaround for the driver bug on dev, and we are hoping to get it on /next tomorrow or Monday.

@MillionMap that appears to be the same driver version as posted in https://community.esri.com/t5/arcgis-online-questions/labels-are-flashing-blinking-in-map-viewer-and/m-p/1396114/highlight/true#M58110 Maybe the computer needs a restart? Or it's possible that the manufacturer for your device hasn't updated the intel drivers if IT is only installing those provided by the manufacturer instead o intel directly. The latest intel drivers for your machine be found here: https://www.intel.com/content/www/us/en/products/sku/203682/intel-core-i910885h-processor-16m-cache-up-to-5-30-ghz/downloads.html The latest version is 31.0.101.2127 which came out 2/1/2024

@FC_Basson in addition to providing the cpu model, can you also provide the report under chrome://gpu?

Hey all, I think we've narrowed this down. What appears to be happening is that for intel driver versions ~30.0.101.1191, there appears to be a driver bug where read-writes to textures are not always synchronized. For some context, labels are allocated some texture space that denotes the state of the label. Before we actually render the labels, we first do a GPGPU pass that modifies the label state. We then use the result of this, (a texture) in another render pass which actually renders the labels. What I'm seeing is that sometimes this texture is not updated before it is used, which is fixed if I explicitly force a synchronization, e.g., by calling readPixels to flush it. This should happen implicitly however. In looking at the differences between 4.28 and 4.29, there appears to be a slight ordering difference resulting in the labeling state modification pass happening slightly later. Rearranging these calls appears to circumvent the issue, & we're currently looking to see if we can install a workaround for this. I still would highly recommend updating drivers if possible as this synchronization issue could affect other things in ways that are hard to really guess upfront.

@MillionMap yes we were able to reproduce this only after downgrading the intel display drivers to 30.0.101.1191. It seems like there is a bug in the intel graphics drivers that affects a cluster of versions around that. We're currently seeing if there's anything we can do on our end to workaround the issue, but as @RussRoberts, upgrading your intel display drivers to the latest version should fix the issue.

@duvoisie when you open the link @RussRoberts posted, does it look this this? Or instead are you noticing that the labels very slowly fade in over many frames? I ask because your machine is using software emulation & might be hitting our VM codepath. If you are able to enable hardware acceleration, does the problem go away?

Hi all! Sorry for the issue, we are working on coming up with a fix, but unfortunately we have yet to find a device internally that we can use to reproduce the issue. Likely it's specific to particular graphics & driver versions. For those who are able to reproduce this, are you able to provide us the chrome GPU report? Go to chrome://gpu & click download report to file. This will give us more information about your GPU (including driver version), and whether chrome is applying any workarounds. It would also be helpful if you could go to https://webglreport.com/?v=2 and see what it says under "unmasked renderer." This will help us to know whether or not the issue is specific to the integrated or discrete graphics. Oftentimes chrome will prefer the integrated graphics.

@LeonAus in 4.22 we added support for repeatLabel, repeatLabelDistance, allowOverrun, and labelPosition (curve / uncurved). We still don't yet have support for all the different labelPlacement options for polylines yet, but we did get some new people on the team recently, so I'm hoping we'll be able to make more progress in labeling soon! Not specific to lines, but better label centroid placement is something we're working on for next release (4.28).
