The program slowed down after the QT version upgrade.
-
I changed the version from QtCreator 4.10.1, Qt5.13.1 to QtCreator 7.0.1, Qt 6.2.3.
(From revision ea829fa6d5 -> da16d778d5)
In the past, I have never experienced slowness when typing in the code-editor not only during compilation but also during normal times, but after the update, the characters I wrote are input after 2-3 seconds, or in severe cases, 10 seconds later.I am using the source used in Qt5 as is in Qt6.
give me an idea
thank you -
Hi,
You might be hitting an issue with the Clang code model. You can try to disable the corresponding plugin.

That is surprising. I take it you exited and re-entered Creator after this change to make sure it took?- I would try running a
topfrom a terminal. Is Creator perchance using lots of CPU time even when sitting idle? - If you start from just an
int main() { }-type program, no file inclusions, is that still slow, or only on your full application?

As I continue to use the program, the delay is reduced and the CPU usage is not high. But the problem still remains.I'm Korean, so I leave code comments in Korean.
Typing in Korean causes more delay than English.
This problem did not exist in QtCreator 4.10.1, but it is a problem in 7.0.1.
It seems that the encoder of the code editor has changed as the version changes. Is there a way to use the encoder from 4.5.1? - I would try running a

You do not have to use Creator 7.x with Qt 6.x. I notice how many issues there are currently reported with Creator 7. You might consider "downgrading" to an earlier version (Creator 6? Creator 4?), seeing if that fixes your "lag" problem and checking that version still has enough support for whatever you are coding in Qt6. -

When using Creator 4.10.1, the problem I'm having now didn't happen.
I just want to fix a problem I'm having with Creator 7.x.Thanks for your attention to my question.
I'll reply to this forum when I fix the problem!@hyur said in The program slowed down after the QT version upgrade.:

I just want to fix a problem I'm having with Creator 7.x.I know this from what you say. I am saying if it is not fixable with current Creator 7.x then maybe if it's important enough you should revert to an older Creator which does not have the issue.....

Qt Creator 7 uses Qt 6.
Qt Creator 4.10 uses Qt 5.How does a Qt Creator 7 build using Qt 5 behave? You can get a binary from https://download.qt.io/snapshots/qtcreator_qt5/7.0/
