Hi, you could try starting Qt Creator from a CMD window (universal
solution #1 for opengl problems) to see if the CPU consumption subsides:
qtcreator -noload Welcome -noload QmlDesigner -noload QmlProfiler

Hi,
I just downloaded Qt-Creator 4.3.0 b1 for some testing.
What immediately struck me was the ongoing action in one thread that
consumes about half a CPU core's performance.
The stacktrace (taken with ProcessExplorer) is
0 ntdll.dll!ZwRequestWaitReplyPort+0xa
1 dwmapi.dll!DwmSetWindowAttribute+0x1cc
2 dwmapi.dll!DwmSetWindowAttribute+0x3d0
3 dwmapi.dll!Ordinal132+0x97a
4 dwmapi.dll!DwmSetWindowAttribute+0x2cc
5 dwmapi.dll!DwmFlush+0x92
6 ig75icd64.dll!DrvValidateVersion+0x139a
7 kernel32.dll!BaseThreadInitThunk+0xd
8 ntdll.dll!RtlUserThreadStart+0x21
Checking on the web I found an entry on the Team Speak forum where they
observed the same issue but with a different Qt-based software.
As described there, I can kill the thread without noticing a real
problem when using Qt-Creator.
I double checked this with both 32bit and 64bit. The problem occurrs in
both versions.
My machine runs Win7
Any ideas?
TIA
Tilman
