Igor, could you please compare Tcl DLLs builds used for testing VC10 and VC14 builds?
Are they same or different?
Where they can be taken ("C:/occt-3rdparty/Windows-64-VC14/tcltk-86-64" on local Jenkins system is not very helpful to find an origin in network)?

On my system OCCT 7.2.0 vc14

TclTk 8.6.2.2 (2016-03-10), coming with OCCT 7.2.0 vc10 distribution:

TclTk 8.6.2.4 (ActiveState) from "occt700products":

So it looks that test memory trend can be affected by execution of Tcl commands (lappend/checktrend) and might depend on Tcl version / compiler used for building Tcl.
In addition, results might be affected by (bugs/memory leaks/memory allocator optimizations in OpenGL driver installed in the system).

They taken locally on testex(s) station. I never take anything from the network

Could you please run tests using NON-ActiveState Tcl build to compare results?

Andrey,

could you please take a look for a possible improvement of checktrend?

I have built current OCCT master (with Visual Studio 2017 Community Edition, 64-bit Release mode) with 3 versions of Tcl/Tk:

A. As downloaded from https://www.opencascade.com/sites/default/files/private/occt/3rdparty/tcltk-86-64.zip [^]
B. ActiveTcl 8.6.4.1 (64-bit)
C. Tcl 8.6.8 freshly compiled from sources using MSVC 2017 Community Edition with dynamic run-time libs (/MD)

and tried executing the test case on my workstation (CPU i7-4790, with integrated graphics Intel HD 4600, 16 GB RAM, Windows 10 64-bit). The results are identical and do not seem to depend on Tcl build:

1. Command "test bugs vis bug79" yields OK; it printed "channel not found" error message on second and further runs (for all builds) yesterday, but not when I re-tried in the morning
2. Command "testgrid bugs vis bug79" yields OK on all runs

Please describe more precisely the sequence of actions, environment (including precise identification of Tcl build), and results in the configuration where the problem appears. I can share my build of Tcl 8.6.8 if you like to experiment with it.

I also advise to try switching between discrete and integrated graphic cards to see if the issue depends on the card used.

I did not understand the meaning of your proposal. Problem is reproduced and on 1080. See attached table

Or if it is not reproduced on integrated graphics Intel HD 4600 you suggest to use integrated video?

The idea is to check if the problem is reproducible only with NVidia graphics but not Intel -- this would suggest that the problem is in graphic driver but not Tcl

I check bug vis on \\revamping1\OCCT without definition -parallel on
GeForce 750 Ti and Intel(R) HD Graphic 4600
Switching was realized by overtaking the cable from the GeForce to Intel

Results shows that on Intel problem not reproduced at all (see attached comparison-GeForce-Intel). It means that problem in NVidia drivers. And on new drivers for 1080 for example amount of bat cases increased. And what we should do? Introduce TO DO in cases with such check.
