Description
When I resize a window with QOpenGLWidget in it with a mouse it tends to accumulate memory which is never freed, not even after a long time. It happens however only on some machines. After about 30 seconds of dragging left bottom corner of the window, the process occupies more than 1 GB of RAM. See the attached GIF.
This is the code I was testing.
#include <QApplication> #include <QOpenGLWindow> int main(int argc, char *argv[]) { QApplication a(argc, argv); QOpenGLWindow w; w.show(); return a.exec(); }
About machine: Windows 10 64-bit, 16 GB RAM, Intel(R) Core(TM) i7-6700 CPU, AMD Radeon R5 430, 4K display Dell.
I tried the same on other machine and this problem did not occur.
