[Qgis-user] QGIS 3.4.3 becoming unusable for me on Windows 10

[David Addy]

Ever since release 3.4.1 QGIS has been a disaster for me, running on Windows
10.
After I upgraded to 3.4.2 I still had problems with everything running very
slowly. (See my post below - 
	QGIS 3.4.2 still very slow to work in Windows 10 by David Addy)

Now on 3.4.3 the same issues seem to be continuing, with the odd crash added
in for good measure.
Opening QGIS on Windows 10 always takes over half a minute before anything
happens apart from the outline box of the QGIS window full of blank space.
Once a project finally loads up any random operation  gets the "QGIS not
responding" message. 
I can scan a map without any problem, moving it around works fine, as does
zooming in and out. But if I want to amend the contents of the attribute
table or change a style in the Layer Properties I get “QGIS is not
responding”. After a long delay it may respond correctly.
This can result in further issues because I may try pressing buttons to get
a response.  After long frustration it might decide to crash.
I use the stand -alone version of 64 bit Windows package, which loads with
QT 5.11.2.
I run a 16 gb computer with Intel i7 processor. It seems to make no
difference whether I have my Kaspersky Security Suite turned on or off.
Frustratingly,   some other users apparently experience no problems with
Windows on QGIS.
Ubuntu users are ecstatic – they work lovely.
If you are on Windows 10 and are still having these sort of issues on QGIS
3.4.3 it would be very helpful if you could add a note to this thread so we
can gauge the numbers involved.  Useful also if you can note whether you use
the standalone package, 64 or 32 bit, and the QT package installed.
Thanks very much.

Sorry to complain, but I just cannot bear to run any work at the moment.
