Description slartibart70 2020-05-13 08:26:19 UTC

I'm using fedora fc31 with plasma 5.18.5/kf5 5.70

Independent on the settings of systemsettings5 > window management > window behavior > titlebar actions > double-click,
the window does not maximize/minimize/shade (whatever) on a double-click inside the title-bar

Instead, the behavior is similar to the 'move window' action (e.g. like clicking Alt+primary mouse key and moving the mouse) 

Double-clicking is indeed working properly inside of windows (e.g. selecting text), so i assume this to be a glitch/bug..?

Comment 1 slartibart70 2020-05-21 15:48:01 UTC

some more information:
this happens only by changing the 'animation speed' in systemsettings5 > workspace behavior > general behavior

(after logoff/login all is fine again, double-clicking on titlebar works as expected. Change the slider setttings - and double click is gone)

Same with freshly installed Fedora 32

Comment 3 David Edmundson 2020-09-14 21:57:53 UTC

QApplication::startDragTime() is getting broken

Git commit 857ee264e62e68dfa7c5ce7086dc6fc4195234a5 by David Edmundson.
Committed on 14/09/2020 at 22:00.
Pushed by davidedmundson into branch 'master'.

Use same default for all places StartDragTime is loaded

On startup we call:

m_hints[QPlatformTheme::StartDragTime] = readConfigValue(cg,
QStringLiteral("StartDragTime"), 500);

on reload we call int startDragTime = cg.readEntry("StartDragTime", 10);

if the startup time isn't set, then if a reload is triggered then it is
reset to a bogus value.

Long term this clearly needs porting to KConfigXT

Oops sorry about the spam everyone I got very confused with bugzilla's interface and then fatfingered the enter key and commited a bunch of stupid changes to a necro'd resolved bug which I have just reverted much apologies.
