Memory overflow with QT 5.1X and Intel GPU graphic
We actually use QT 5.1X on Intel NUC with
Intel(R) Core(TM) i7-8559U CPU @ 2.70GHz
Intel(R) HD Graphics (Coffeelake 3x8 GT3)
OpenGL ES 3.2 Mesa 17.2.3
The app display pictures using QML image: and QQuickImageProvider on 2 windows.
We are currently experiencing a big problem of memory consumption.(All memory is consume)
Has anyone ever encountered this problem with the Intel HD Graphics ?
Your help is really welcome !
Qt 5.1X is a bit vague, what exact version are you using ?
Can you show the code you are using ?
Did you try updating/downgrading your graphic card driver ?
Hello, the versions :
Version : QT 5.10.1-0-201802092256
CentOS Linux release 7.5.1804
OpenGL version string: 3.0 Mesa 17.2.3
00:02.0 VGA compatible controller: Intel Corporation Device 3ea5 (rev 01)
OpenGL and Intel GPU seems to be strongly linked.
The intel driver goes with the Centos version.
Can you check whether you have the same phenomenon with a more recent version of Qt ? And if not, with an older one ?
We have same problem with QT 5.8, Qt 5.11.0, QT5.11.1 in 2 screens and 2 windows
With 1 screen and 1 windows not problem.
Is it not a problem or is the leak taking way longer to eat all the memory ?
It is a big problem.
On2 screens only, each time a image is updated the memory is consume and not freed.
After 1 minutes 32 Go of mem are consume and after the swap and computer can not run.
What I meant was: is it really "not a problem" with only 1 screen and 1 window or is it just the memory leak that is way slower in that setup ?
With only 1 screen and 1 windows we don't see memory leak.
