Qt5 dummy widget with size 75x32 is visible on app start

(1/3) > >>

Please see the description of the problem + youtube video.
I  found the Qt5 WS part which creates such a window: posted there to Github.

How can we avoid that tiny window?

Can we have new IFDEF for that dummy-window?
This place must be changed

--- Code: Pascal  [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---  {$IFDEF HASX11}  if QtMainWindow.IsMainForm and not Application.HasOption('disableaccurateframe') then  begin    (*    AWindowManager := LowerCase(GetWindowManager);    //Kwin,Openbox,wmaker-common - ok    if Application.HasOption('hideaccurateframe') or not    ( (AWindowManager = 'kwin') or (AWindowManager = 'openbox') or (AWindowManager = 'wmaker-common') ) then      QtWidgetSet.CreateDummyWidgetFrame(AWinControl.Left, AWinControl.Top, AWinControl.Width, AWinControl.Height)    else    *)    QtWidgetSet.CreateDummyWidgetFrame(-1, -1, -1, -1); {only mentioned window managers literally move dummy widget out of screen - no flickering}  end;  {$ENDIF}

I cannot replicate this problem on a Debian Bullseye running KDE Plasma with the Qt5 version of tomboy-ng.  Is its OS specific ?  What OS are you testing on and do you know what OS your end user is using ?


It is Window Manager specific. It is visible under configuration of GitHub user who reported it.

Plasma 5.24 in KDE Neon; KWin.

It must be more than Window Manager specific, my Debian KDE Plasma also uses KWin as Window Manager (of course, its the default).  So maybe specific to 5.24 ?

Apparently, I'm using KDE 5:20.5 (I say apparently because the version reported by synaptic is 5:111 but kwin gets 4:5.20.5-1 ??).   Anyway, Debian unstable, right now, does have 5.24, I will see if I can get it going ....
