Excellent news that the Welcome page uses widgets, I should download the 4.3 beta and try it!
And also remember to unlearn my "universal solution #1" :-) /Rgrds Henry

Hi,

-noload Welcome is not required anymore, since the Welcome Page was 
reimplemented using widgets.
An alternative to avoid OpenGL issues on Windows is "set QT_OPENGL=software".
I cannot reproduce the issue on my Windows 10 setup.

Kind Regards,

Betreff: Re: [Qt-creator] QtCreator 4.3b1 background thread running?

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

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
