[Qgis-user] OpenCL Crash

[Nicolas Cadieux]

Hi,

Activating OpenCL in QGIS 3.4.3 causes a Qgis crash (Settings -> Options 
-> Acceleration -> Enable OpenCL acceleration = crash.  I am on Windows 
10_64, Osgeo4W installations.   Video Card is an old GTX260 with OpenCL 
1.0 activated (with cuda 1.0) with the latest drivers (342.01).  I also 
installed the Intel OpenCL 18.1 Runtime for my CPU i7 6800K in case the 
problem was with the old GPU.  The Acceleration windows is blank below 
the "the following OpenCL devices were found on this system...". Maybe 
that is only because "Enable OpenCL Acceleration" box is not clicked? 
This issue is closed in bug report 20363. 
https://issues.qgis.org/issues/20363.  I added my feedback to the thread.

Does anyone have any Idea how to trouble shoot this?

Thanks,

Nicolas
