Labels flickering on maps in ArcGIS Enterprise 11.4

Joshua-Young — Thu, 19 Dec 2024 18:25:47 GMT

When a map loads in the Map Viewer or Experience Builder several labels will flicker on the map. Sometimes they will stop flickering after a few seconds of the map not moving and other times they just keep flickering. Layers with the flickering labels are feature services from a SQL Server hosted enterprise geodatabase Graphics drivers are up-to-date, and we are on ArcGIS Enterprise 11.4. This is a very distracting issue.

Anyone else experiencing this and know of a fix?

It's almost like its stuck in a render, re-render cycle, notice how it disappears and then seems to draw the 4 than a 9 that's 0 and 1 ? (401)?

I'm curious if you hit F12, and look at the console while this is happening are there any messages you find?

Hi @TimWestern - I'm having the same issue (flickering text in the MapViewer, Enterprise 11.4) and when I checked the Consol I'm getting this error:
Failed to load /portal/apps/fonts/t...regular/0-255.pbf:1 resource: the server responded with a status of 404 ()
This indicated that maybe the font isn't on the portal machine?

I tried changing the labels to a Windows 11 default font (Arial) and the issue continued. I'm wondering if it's not an issue in the font path?
Please note - this is oly happening on labels created AFTER the update - labels that were present in our 11.1 maps are fine.

Based on that in the console it either is not in the machine, has not been installed via npm somewhere, or if its looking to load it from a remote site the url may be wrong.

You may try looking in the Dev Tools of the Browser (F12) then go to the network tab and see if you can find that file's 404 message and look at the request parameters to figure out which it is.

This screen cap has me wondering if something is getting stuck in a never ending refresh/render cycle.

@CUBoulder_GIS_Office May I ask what type of graphics driver/card/chipset you are experiencing this on? I am also experiencing this flicker on my machine but only in one label dense web map.

One a desktop computer with Intel and NVIDIA graphics does not have the issue. Another laptop with Intel and NVIDIA graphics does have the issue. Both computers are up to date on drivers, we are using the same web browser, and looking at the same web map.

Do you know if the Intel drivers are Intel Arc or Iris Xe drivers?

Re: Labels flickering on maps in ArcGIS Enterprise 11.4

Joshua-Young — Mon, 07 Apr 2025 19:01:47 GMT

The laptop that is having the issue is Intel Arc. The desktop without the issue is Intel UHD 770.

Same here, multiple laptops with Arc Drivers are seeing flickering on a web map. Non Arc Intel graphics appear to be working just fine.

Experiencing similar issue here. Cleared cache, changed browsers, updated drivers to no avail. This issue only impacts our newer laptops which have Intel Arc Graphics and Nvidia RTX 2000.

Update: disabling Intel Arc Graphics/Forcing browser to use Nvidia GPU solved the flickering issue for me.

I've seen some strange things with recent intel drivers in various apps. This has me wondering if its a browser issue?

If you are using chrome and seeing this? If you go to the three dots > settings and then click on system, does your machine have graphics acceleration enabled when available?

If its on try disabling it and see if that fixes the issue?

Turning hardware acceleration off in Chrome does fix the flickering but results in much poorer performance on the application. We also experienced this flickering inside of Edge and Firefox browsers.

That is most puzzling.

Dell just released a new Intel graphics driver today for our laptops and after installing the flickering went away even with hardware acceleration enabled.

Yes. Same here. Disabling hardware acceleration led to severe performance issues with our webmaps. Also, it didn't seem to totally "fix" the issue for us. Instead of the labels flickering, they would slowly fade in. Some still didn't appear at all. We tried various browsers and had the same results. Since forcing Chrome to use our dedicated GPU instead, we've had no issues and increased overall performance.
