Text Glyphs overlap, vcpkg build
-
Hi guys,
I am using Qt through vcpkg manifests mode in Microsoft Visual Studio 2019 (CMake Project with vcpkg toolchain file, triplet x64-windows). Here is my vcpkg.json and my main.cpp (minimum working example showing the problem):
{
"name": "test123",
"version-string": "1.0.0",
"dependencies": [
{
"name": "qtbase",
"default-features": false,
"features": [
"doubleconversion",
"gui",
"widgets"
]
}
]
}#include <QApplication>
#include <QMainWindow>
#include <QPushButton>int main(int argc, char* argv[])
{
QApplication app(argc, argv);
QMainWindow MainWindow;
MainWindow.setCentralWidget(new QPushButton("Hello World!"));
MainWindow.show();
return app.exec();
}The text glyphs are just rendered on top of each other:
If I put a single character on the push button it is shown correctly:
As I am not building windeployqt.exe, I manually copy the folders in the <build-folder>/vcpkg_installed/x64-windows/Qt6/plugins folder to the text123.exe folder.
I have run out of ideas on how to solve this or find its cause. Any help would be greatly appreciated. -
The behaviour for Qt 5.15.0 and 6.1.1. is as-expected on my Linux box.
You are building with with version of Qt, 6.x?
Are you certain you have the matching version's plugins.
What part of the display is a clickable button in your example? That is, does the QPushButton fill the main window client area, or just where the letters are? -
Inside "(...)/vcpkg/buildtrees/qtbase/x64-windows-dbg" I found a "config.summary" file. Maybe its output helps to identify the problem or any missing libraries:
