Hello everyone!
I’m having issues with drawn lines blinking when driving. We are using track-recording to draw green lines over roads that we have registered, but the lines keep blinking while moving (see video here: Dropbox ).
Does anyone know any settings or tweaks we can do to stop the blinking?
Thanks!

@Usman_Butt , this could happen if the layer you used for tracking has labels enabled or acts as an obstacle to other labels. When that’s the case, it triggers a much heavier canvas reload every time a vertex is added to the line being tracked, and causes flashes.
Thanks, we will try to remove the labels at these zoom levels and see if that helps.

@Mathieu_Pellerin after removing the labels we still see the same issue.
It seems to be worst when driving on top of a previously driven road-line in the same active tracking session.
Any other ideas?

@Usman_Butt , feel free to attach your project here, we can have a look.
@Mathieu_Pellerin can I share the project with you on Qfield Cloud (it’s through there we use it)? Or would you prefer it packaged?
@Usman_Butt , via QFieldCloud is fine. What’s the project title?
@Mathieu_Pellerin it is called Cowi_DDG2026/Bil_04_DK. Admin is kmdCOWI. All of the projects in there are having the same issue. My work account is in there as well UNBT_cowi.
OK, first, I can see one easy optimization you could do, which is to switch the packaging action of any vector layer that are meant to be read-only from ‘offline editing’ to ‘directly access data source’ here:
That will reduce the generated offline editing geopackage. For e.g., if you can threat the Vejmidter layer as read-only and avoid offlining that, it’ll help.
Then, looking at the video, I see your map canvas is set to follow your position and compass. If you disable that altogether, or follow only your position (the settings is in QField settings’ positioning panel since QField 4.1), does that help?
Following the position + compass can be draining and cause a lot of canvas refreshes.
