MSVC2017 64bit compiler VS. MinGW 32bit compiler
I'm using my Qt Creator with the two Compilers MSVC2017 64bit and MinGW 32bit.
For my current Project, I want to use the MSVC2017 Compiler, but the built Software (compiled in release-mode) is laggy af. (and I don't think there's much of computational work done..)
But when I compile the exact same Project with the MinGW Compiler, the Performance issue is gone and everything works fine.
Does anybody have an idea what the Problem could be?
@Pagiraff Without knowing what you app is doing it is impossible to say. Also it could help if you would say when and in which situation it is laggy.
Ok sorry, here are some informations about the Software:
It's purpose will be to load/save data out/to txt files and visualize them when loaded. I've set a MDI area in the MainWindow where you can call different SubWindows (e.g. one for Import, one for visualization Settings, etc.).
Now for MSVC compilation:
When I only have one SubWindow open in the MDI area, resizing it (drag it at the Corner) causes a visual lag.
Also when I enter a path to search for certain files on drives (self implemented method), there's a noticable delay until I can perform another search...
All this Actions work perfectly fine when the Software is compiled with MinGW
@Pagiraff That's interesting. You could check whether this is a known issue here: https://bugreports.qt.io/secure/Dashboard.jspa
You can file a bug report if this is not yet reported (preferably with a small example project demonstrating the issue).
