QT Creator is very slow when edit QML file.
-
Hello everyone!
I'm currently developing GUI for the retail store. It's just a simple GUI. First, I interact with labels, buttons,..., everything very smooth. Every click response quickly. But now the delay after click, drag items,.. every manipulation delay for 2-5s. I have the latest system with Intel i5-1135g7, Intel Iris Xe, 512 GB high-speed SSD, 8GB DDR4 bus 4267MHz,...The project remains the same but it just suddenly become slow, lagging,... When I move the whole project to a weaker laptop, It still handles very smoothly. I wonder why? I also try to re-install and config the plugin as the weaker laptop but nothing change.
A video show my problem:

Report it on Qt bug tracker please.
Also, Qt Creator 4.15 has just been released, maybe try it out, perhaps your issue is fixed?

Thank you for your response! I realize that whenever I move, edit the label, button in QML, Task manager report that only uses 14% CPU . We desire the Qt Creator use 100% CPU usages when debugging right ?. Is there any option that I can increase the CPU usage of QT Creator? Is it normal when missing LLVM 64 bit as the picture below sir ?

After a while. I figure out how to solve this problem. The QT Creator slow, lagging perhaps since I copy my friend's qml files. I try to uninstall QT Creator then Re-Install it then set the option as default like this. Uninstall then reinstall didn't help me reset the default setting of QT creator. I must set every field manually as the picture below then it smooth!
