Hi guys,

upgrade to Plasma 5.9.4 fixed that bug(s):
https://forum.kde.org/viewtopic.php?f=67&t=139374

but it seems to be back, accompanied by frequent plasma crashes:
In the folderview widget, when mouse cursor is hovering a file, it does not unselect when the cursor leaves that file. To make no selection is no option for the moment. This is in folderview mode AND workspace mode. So folderview widget is useless.
Waiting for 5.10.3 Bugfix?

I can't reproduce this but there are few bug reports with recent fixes:

Bug 380354 - Drag select does not stop on releasing left mouse button in Folder View Widget : https://bugs.kde.org/show_bug.cgi?id=380354
Bug 380982 - folder icon not properly deselected after closing expanded folder view : https://bugs.kde.org/show_bug.cgi?id=380982

here this bug is still reproduceable:
1) adding a folderview widget to the desktop, be it workspace-mode or folderview-mode
2) after a few clicks in it, the selection won't be dropped as if the left mouse button were constantly pressed


Relevant bugs are mostly marked as fixed such as this: https://bugs.kde.org/show_bug.cgi?id=377441
there is a proposal to fix it: https://cgit.kde.org/plasma-desktop.git/commit/?id=b7ce1a4bc1d050ee03837bac77d1a31c3b84c175
I don't know how to apply this and wether its the same bug.

This is not a "proposal", but an actual commit. And it is part of 5.8.7 and 5.10.

Your current problem is likely related to the bug reports Rog131 mentioned:
https://bugs.kde.org/show_bug.cgi?id=380982
Will be fixed in Plasma 5.10.3 (to be released next Tuesday) by https://cgit.kde.org/plasma-desktop.git ... 38f32d1081

https://bugs.kde.org/show_bug.cgi?id=380354
A problem in kdeclarative caused by a change in Qt 5.8 and higher.
Will be fixed in Frameworks 5.36.0 (to be released in about two weeks) by https://cgit.kde.org/kdeclarative.git/c ... ac9f8ab542

If you want to apply those patches, you need to compile plasma-desktop or kdeclarative yourself.
Or ask you distribution's packagers to add them to their packages.

Thanks for information wolfi323. Patience is likely the solution in this case.

In the current update of Bugfix (Plasma 5.10.3) it hasn't been fixed yet.
So folder view applet is still not usable on my side.

If you want to apply those patches, you need to compile ... kdeclarative yourself.

I should do that, but its my first time, so i could need a bit of a guidance.
What i did til now:
1. got the PKGBUILD of kdeclarative: https://git.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packages/kdeclarative
2. got the patch: https://cgit.kde.org/kdeclarative.git/commit/?id=fd4d41bd65fd3a3190471476104b0bac9f8ab542

Roughly: i intend to run makepkg > apply the patch (with DIFF) > install the edited kdeclarative as a substitute for the former, buggy version
But the exact procedure is not clear.
I would appreciate any help beyond of https://wiki.archlinux.org/index.php/Creating_packages

EDIT 2017-07-10
Todays update (KDE Applications 17.04.3) fixed the issue

Rather KDE Frameworks 5.36.0 I suppose.

KDE Applications 17.04.3 has not been released yet (it will be released on Thursday), and that issue has nothing to do with KDE *Applications* anyway.

yep wolfi323 you're right
