[QGIS-Developer] Problems running 3.2/3.3

[Patrick Dunford]

Good day all

I have Qgis 3.3 latest master installed on a desktop and a virtual 
machine. The desktop is running Debian 9.3 and the virtual machine is 
running Debian 9.4

The VM runs 3.3 as a new install and has no problems running it, 
everything seems to work normally.

The desktop has a lot of problems running 3.3 or 3.2 with the same 
issues in both. It was upgraded from 3.0 which it had no difficulties with.

The main issues seen are:

* only a few layers can be displayed at a time. It will not display all 
the layers at once.

* attempting to save a geopackage produces error messages like the ones 
below

2018-07-09T02:16:08     CRITICAL    Layer wmwtWL : OGR error changing 
geometry: feature 12 not found
2018-07-09T02:16:08     CRITICAL    Layer wmwtWL : OGR error changing 
geometry: feature 13 not found
2018-07-09T02:16:08     CRITICAL    Layer wmwtWL : OGR error changing 
geometry: feature 84 not found
2018-07-09T02:16:08     CRITICAL    Layer wmwtWL : OGR error committing 
transaction: COMMIT transaction failed: cannot commit - no transaction 
is active

and it undoes all the changes in the map canvas so they are all lost. 
there are no permissions issue as project files can be saved fine.

The desktop has very little other software on it except Gimp 2.9 
(AppImage) and Gimp 2.10 (Flatpak) on it and it's a complete mystery to 
me how there could be any other software on this computer that might 
conflict with Qgis.

Any ideas?
