Qt Creator strange behaviour. How to fix it?

[SGaist]

Did you check with the next beta ?

[bogong]

@SGaist Not, I've not been checking beta. Just fully installed 5.12.2 - the same result.

@Gerhard What does it mean?

[J.Hilk]

@bogong Might be a long shot, but it wouldn't surprise me that much if it's the issue.

Can you try disabling the clang code model and check if the issue goes away ?

QtCreator-> help -> About Plugins->ClangCodeModel

@J.Hilk I will do it today and reply.

Beside all of it new portion of strange behaviour ...

The highlighting ...

After updating onto 5.12.2 I've got this issue:

• The highlighting sometimes without any reasons became broken and showing like on image;
• The broken variables in other codes became unavailable and showing like undeclared or mistaken

Only restart of Qt Creator fixing it. But in about hour it's happening again ...

Sometimes this kind of behaviour switching me into "WTF" mode! :-) At this time I am happy about working alone because of a lot of uncensored terms :-)

[bogong]

@J.Hilk Just switched off QtCreator-> help -> About Plugins->ClangCodeModel The first issue became solved. All is OK with duplicating. The first impression of the switching off this plugin - QT Creator became working MUCH FASTER! It's working without unreasonable pauses.

But next portion of strange things above :-)

@J.Hilk Look on screenshot. I've got catching the problem!

The problem with duplicating kits appeared again. Only deleting *.user.pro and reconfiguring whole project solve it. I am not doing anything special.

[bogong]

@J.Hilk Just reconfigured again. Now problem hasn't been disappearing. In "Build&Run" still broken kits.

The button "Delete" in Kits inactive. I couldn't remove broken kits.

[bogong]

@J.Hilk After killing Qt Creator configs (~/.config/QtProject) and total reconfiguring - again OK.

This is the contain of the directory where located kits just after reconfiguring:

!!! AND THIS IS when it happening:

When I am working I do not change anything in settings. Just closing Qt Creator at evening time and when start it at morning having this kind of troubles (mean restart Qt Creator).

@bogong
I'm afraid, I don't have much experience with QtCreator and it's inner workings. I'm using it, and that's about it.

Maybe someone else has more insight on this. Or you take to the QtCreator mailing list. there are the developers active and they might be able to help you more.

From personal experience, I can say, try completely uninstalling QtCreator and reinstall it. in 90% of all my issues that I had with it, were fixed that way.
Time consuming, I know :(
