6 years ago I'll check in the morning. It's a Citrix Win7 VDI so that may complicate things. I'm trying to get the VDi updated to Win10 and if that fixes it I'll be happy enough...

6 years ago Interesting, it might yeah. I don't know anything about Citrix, is there anywhere I can see the OpenGL and DirectX support level documented? Was Qt 5.6 problem-free here? (I guess so).
The way 3D works in Qt works these days (but this has been the same since 5.6 and even before) is that it tries to use OpenGL (called 'desktop' mode) via your GPU vendors drivers and if those fail to provide the necessary features then it falls back to something by Google called ANGLE (almost native GL emulation) which builds on top of DirectX (11 I believe).
I wouldn't expect a lot to have changed about this setup between 5.6 and 5.9 (perhaps QtWebEngine - which now replaces QtWebKit - needs richer framebuffers that your OpenGL drivers do not support, or perhaps ANGLE needs DirectX 11 instead of 9).
If you can run Spyder against 5.6 and use process hacker 2 to view the loaded DLLs we should be able to determine whether it's falling back to ANGLE or not. You can also force ANGLE in cmd.exe by doing:
set QT_OPENGL=angle
and you can force 'desktop' mode with:
set QT_OPENGL=desktop
It would be interesting to know whether either of these work / do not work with spyder on both 5.6 and 5.9 if you have time to do these tests?
Finally you could try moving C:\Windows\System32\D3DCompiler_47.dll beside the python executable to see if that changes things. If you don't have this file (you may be able to get away with a different version of it, perhaps try renaming it to _47.dll though?) then there's no chance that ANGLE mode will work.

6 years ago As a final fallback, I could provide opengl32sw.dll (it comes as part of mesa) but when it's used the performance will be terrible since it's a software rasteriser so before I consider that I'm afraid you are a useful test-case to figure out these compatibility issues; we want the best performance for as many people as possible.

...so with 'desktop' there is no output in the console - just a python segfault in Qt5WebEngineCore.dll. With 'angle' the segfault is in ucrtbase.dll
I do appear to have C:\Windows\System32\D3DCompiler_47.dll:
Copying that dll into my sys.prefix didn't appear to change anything - same output as for angle and ucrtbase.dll exception

6 years ago BTW, we've been a little lucky with out PyQt based applications in that they work with PyQt 5.6 and also with PyQt 5.9 and our dependencies are set so as to allow either to work so you should be able to still use new versions of spyder, navigator and orange3 with PyQt 5.6.
You will run into trouble with the upcoming RStudio 1.2 which absolutely needs Qt 5.9 (for QtWebEngine which is basically Chromium).

6 years ago A Kivy bug related to using ANGLE on Citrix VM with some hints about multisampling/antialiasing but I suspect we are first of all running into a need for OpenGL >= 3 and Citrix providing only 2 (if any at all) - if you can figure a way to check the GL level that Citrix provides here I'd appreciate it. I think the subsequent ANGLE failure could be the multisampling/antialiasing issue.

6 years ago Hey Carlos, no it doesn't, at least our builds do not and have not (at least none I have built or seen). I need to add it to the qt package anyway. It should be safe enough to do since it's only used when two better (hardware accelerated) options fail to work.
This bug is likely due to needing a more modern graphics stack for Qt 5.9 than Citrix VM provides (I've provided a good amount of links here if you want to verify or dispute this claim).
@dhirschfeld, can I trouble you to also try the other opengl DLLs in that link I provided? I would like to use the most recent one (the 2016 one I think) but need to know that it works well enough, so if you can test as many Qt apps as possible I'd be very grateful. I have RStudio 1.2 pre release builds on anaconda.org/rdonnelly too.
I know it's cheeky to ask for so much from you but if you can also run these tests in a 32 bit install with the 32 bit DLLs (obviously!) that would be really great. I don't know how else I can test this unfortunately.
Thanks for asking Citrix about this too!

6 years ago The qt apps I know of are anaconda-navigator, spyder, orange3 and RStudio. Conda-forge may have some others but they may be incompatible for other reasons (pyqt ones might work, C++ ones stand no chance without recompilation).

5 years ago Hi Ray, sorry I never did get around to testing with 32bit. I can't use my current desktop to do so but I can probably get a different VDI to test with. Will try to do so this week and let you know there results...
After updating to the latest qt spyder is now broken (win64/py36):
Issue moved from spyder-ide/spyder#6938
@ccordoba12 suggested the issue to be with the qt package which should be packaging the missing
opengl32sw.dll
