Unsolved Widget jumps/flickers when hide another widget
-
Why do you expect that it works with an older version (except it would be a regression). Update to 5.15 and check again.
-
@Christian-Ehrlicher does not make sense to try because project uses Qt5.12.5.
-
Then you have to live with it. Neither 5.12.5 will be fixed nor looks it like a problem in your code.

Hi
I tried with Qt 5.9.1 in linux and i cant get it to do it.
-
@mrjj, @Christian-Ehrlicher thanks for checking. i see that is not reproducible on your side.
I did more checks: with qt 5.15.2 and 6.0.1 and on my side this bug is still presented. Also i tried on VM with KDE qt 5.12.8 only there it works normally. -
So even with 5.15.2 you see this on your systems?
Also, the Latitude 7400 is not very old, is it ?
-
@mrjj yes i see this effect on 5.15.2 and 6.0.1. I would say Latitude 7400 is fresh.

Do they have anything in common gfx wise ?
Like both using intel driver or similar ?It cant really be the app as its as basic as possible so i think it some sort
of gfx glitch but I also tried on old laptop that has 3d issues but
not even there i could get it to do it.Looking at the video , it seems it has an extra redraw while the layout adjusts.
Im not really sure how we can work around it as not sure why we can see it in the video.
-
@mrjj yes both laptops use Intel UHD Graphics. it can be cause of this behavior. Before this post i tried to find similar discussions in the internet and there are of few of them. Seems to me this issue is kind of single cases and hardware/driver depended. I think, if i have spare time i will investigate it deeper.
-
well, it could be something like that.
It might not happen that often either.
At least, I could not get the demo code to show even trying around
different hardware.
