I'm facing a similar issue as #19761 and #20459 with a very basic example.

The project (attached) has only one layer (Spatialite, point).

To reproduce the issue :
  • After the project is loaded, I use the identify tool on one point. The attribute form opens normally. I close it.
  • I try to identify an other point, the attribute form opens again normally. I close it, but this time the task "Identify feature" in the task manager doesn't stopped, and I can't stopped it manually.
  • After that, I can continue to use the identify tool normaly (the forms opens), but the corresponding tasks "Identify feature" are not removed from the task manager.
  • I can't close QGis because of the first "permanent" "Identify feature" task. I have to kill the application with Windows task manager.
Conditions :
  • OS : I reproduce this bug only on Windows (tested on 7 and 10). I have tested it on Debian and I couldn't reproduce the issue.
  • Data provider : I observe the issue only with Spatialite layer. I have also tried with Shapefile and PostGIS layer : there was no issue.
  • QGis version : the issue exists in 3.4.0, 3.4.1 and 3.4.2 QGis versions.
Others details :
  • The bug can be reproduced whithout clicking on a point. Using the identify tool and clicking anywhere has the same result : the second click produce a "permanent" "Identify feature" task.
  • If I reproduce the bug whith the layer in edit mode, when I stop the edition, the map refreshs and the points of the layer disappear (they are not shown).

Best regards.

Would you mind testing with QGIS 3.4.2 please? It should be fixed. Thanks.

#2 Updated by Bertrand Roux over 1 year ago

I already tested on 3.4.2 and the issue is still here... (I didn't find "3.4.2" value in "Affected QGIS version" list)

#3 Updated by Giovanni Manghi over 1 year ago

  • Affected QGIS version changed from 3.4.1 to 3.4.2

#4 Updated by Giovanni Manghi over 1 year ago

Have you tried on a new/clean profile?

  • Priority changed from Normal to High

#6 Updated by Bertrand Roux over 1 year ago

Yes, I tried on a new computer (VM) on which I installed Windows 10 and after QGis 4.3.2 (so there was no previous version of QGis ans the user profile was new).

#7 Updated by Giovanni Manghi over 1 year ago

Does it works as expected on 2.18?

#8 Updated by Bertrand Roux over 1 year ago

I don't know for 2.18. I have to install it to test.
I'm sure it worked with versions 3.0 and 3.2 since I did tests in may and august. But I don't remember if the task manager already existed in these versions.

This bug report is very odd -- that task was COMPLETELY removed in 3.4.2! See https://github.com/qgis/QGIS/commit/073c5be69f612362afab6e93ff2f8c731d20bbf8 . There's NOTHING in the 3.4.2 source which even uses the "Identifying features" string anymore. :O

Can you confirm how you installed QGIS?

#11 Updated by Bertrand Roux over 1 year ago

I have used the installer http://qgis.org/downloads/QGIS-OSGeo4W-3.4.2-1-Setup-x86_64.exe I dowloaded the 26-Nov-2018 at 08:32 (GTM).

Today, I see that there is a newer file QGIS-OSGeo4W-3.4.2-1-Setup-x86_64.exe (26-Nov-2018 15:44, http://download.osgeo.org/qgis/win64/). I download it and install it. The issue doesn't exist anymore !

Sorry for bothering you with that... That was a false alarm.

Many thanks for the help.
