Windows Qt Creator freezing within VirtualBox

[mrjj]

Hi
Used VBox 5.2.28 and win 7 64bit and so far i have not seen
any freezes.
I noticed that a newer version has come out. it could be worth trying.

I will use it some more tomorrow to see if i can get it to be funky.

@mrjj you're the best :)

Actually, i must say VBox actually feels
faster with a Windows 7 than it does in vmware.
I notice that QML was a bit unhappy about the openGl.
I did install the addons but didnt enable openGL in settings (somewhere)

Do you have openGL on ?

@mrjj said in Windows Qt Creator freezing within VirtualBox:

I don't even know how to do that.

These are my machine graphics settings:

When installing the Guest Additions, I did not choose the experimental Direct3D support.

I'm currently indeed reinstalling Qt on one system. Let's see how it goes.

Edit: on first start, following dialog appears:

So indeed no OpenGL

And after running one of the examples, I have these in my Application Output:

So OpenGL could really be a problem.

Hi
Ok, it is on. (3d -Beschleunigung )
But i guess its not good enough for QML. hence the warning

I have 4 cores assigned. Are you using it on ryzen and have like 8 ?

So far no freezes.

Im going to mega update win 7 and see if that makes a difference.

1 GB updates..:)

Probably. I disabled the two plugins, as I don't need them.

I have 4 cores assigned. Are you using it on ryzen and have like 8 ?

No, only six cores. I'm running it on a Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz notebook.

After the re-installation (Qt 5.12.3 MSVC2017, Visual Studio Build tools) it works quite well. I've compiled QtCreator from source (takes 17 minutes and is therefore faster than on the Linux host - interesting btw.) and debugged a smaller program. So far without crashes or freezes.

I will try next time on my development machine (the Ryzen), but I really think it's just some installation hickup.

@J-Hilk: I guess I owe you a beer @ Qt World Summit ( @mrjj: I hope we can have one too :))

Throw away comment: I use VirtualBox, but on Windows host for Linux guest. In this VB (at least), on Settings, Display tab, there are options for both 3D and 2D acceleration. I found I had to switch both off (i.e. including the 2D) to get reliable Qt application/Creator behaviour. Just a thought if further odd behaviour...?

[aha_1980]

@JonB Thanks for the hint, I will take it into account if the reinstallation does not help.

[J.Hilk]

@aha_1980 ;-) I'm all for it, of course.

I now reinstalled Qt and Creator on my workstation too.

So far, no freezes - let's cross fingers.

Thank you all for your help :)

That is good news.
Besides getting slower after being patched to death,
i did not experience any freezing.
