Can't see Items List of QComboBox, when use showFullScreen

@mrjj Hi
Thank you for replying so quickly!Yes, it is very odd.
I find there is one more widget doing the strange things. It is QDateTimeEdit. It acts the same with QComboBox.
What's more, even though I can't see dropdown list, I can select one item by clicking.

Hi
Would be possible to test with newer/newest version of Qt ?Also, did full screen work at some point but stopped or this is from beginning ?
Im wondering if it could be some sort of gfx driver issue or font rendering issue.

Hi,I haven't install newer version of Qt. So I can't test it now. Could you help to test that?
Full screen doesn't work. At least, I haven't seen that it works. So I think this is from the beginning.
If it is some sort of gfx driver issue or font rendering issue, how could I confirm it and how could I fix it?
Thanks!

hi
well i tested with
https://www.dropbox.com/s/3hlqg2hqm22m3gu/testfullscreen.zip?dl=0
and it works as expected.
Could You try same sample ?Well you can check if any new drivers are available for your gfx card if not already done. ( like from Intel or nvidia)

Hi,Thank you very much!
This sample works.
Maybe, my program is a little complex. I should debug my program to find out the problem.
@Qingshui-Kong
Hi
ok, that is good news. \o/
Its just a normal bug then.
Do you start app at once in full screen or
you toggle it ? ( like sample) -

HiI start app at once in full screen. I use w.showFullscreen() in the main() function.
@Qingshui-Kong
hi
ok, i tried with sample that way too but still there are items.
So it seems its something in the real app code.
if you just do // w.showFullscreen()
then there is items visible ?
How do you fill the items to the combobox. any chance they can be empty strings for some reason ? -

Hi,
Yes, there should be some bugs in my app code.If I use w.show() in the main function, it works.
I am sure that I have fill the items to the combobox. And I can select them by clicking, even though I can't see them.

This is a known limitation on Windows, I suggest you have a look at https://doc.qt.io/qt-5/windows-issues.html#fullscreen-opengl-based-windows as that describes the problem in more detail and gives a solution which you can use.
