[Qgis-user] QGIS 3.10 not responding
Hello, Is it common to have QGIS 3.10 'not responding' on Windows 10? Anything one would want to check if this happens a lot?

Re: [Qgis-user] Relation widget values
Hi, No workaround. QGIS makes relations on the tables that are loaded in QGIS. You will always need both tables.

[Qgis-user] Relation widget values
Hi, I've a question regarding the Value Relation Widget under Layer Properties/Attributes Forms. Making the configuration work very well to bind a field to a list of values of another table in the project. When all is done, I make a qlr file to save all the layer definitions. The problem appears when I reload the qlr file without all the relational tables. The fields are bound, but the values aren’t displayed. To make this work, I need to add the relational tables to the project too. Does it have a workaround or an alternative to make it work without adding all the tables to the project? I saw in the qlr file that the connection to postgresql and all needed information are in the file to make it work. Database: postgresql 9.6 QGIS version 3.10.3 Layers and tables are in the database.

[Qgis-user] Fwd: Problem with editable postgis view in Qgis3
hello, I'm using an editable view (idrographic graph ) created in postgis in a Qgis 3.4.12 LTR project. The view with triggers works fine, I can manage features and attributes insert, update or delete , but after inserting or updating a new line it seems that Qgis doesn't refresh the spatial index, I see the feature, I can identify attributes but I can't change the geometry (e.g move vertex) or even snap to that with new features. If I open the view properties and then close, Qgis start a sort of indexing and everything works again. Does anybody know this problem? The same view in Qgis2.18 works without problems, but even in the 3.10 LTR the bug remains.

Re: [Qgis-user] Qgis crashes while loading WMTS layers
Hello Patrick: Which desktop manager are you using? Some months ago,I reinstalled my buster machine with the default Gnome, and found, like you, repeated crashed of QGIS in all kinds of unrelated situations. After trying many updates, recreating QGIS projects, etc, I decided to try KDE. And voila, all the troubles disappeared. I have since followed the upgrades thru 3.10 to 3.12 and no issues have appeared. I can't even guess what the problem is: maybe some clash between QGIS and the gtk libraries used by Gnome? In any case I'm back on KDE and enjoying it. On 13/03/2020 8:24, Patrick Dunford wrote: In the last few weeks I have been doing a lot of testing with various test environments.

Version 2.18 and earlier almost never crashed with excess layers, usually all that would happen is a layer would be displayed with invalid data. However, crashes have become the norm with 3.x versions of software.
