Unsolved Memory overflow with QT 5.1X and Intel GPU graphic
-
Hello everyone,
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 !
Thanks ! -

Hi,
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 ?

Hello,
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.
