Description lnxusr 2012-08-02 06:02:16 UTC
There is a slight 1.5 to 2 second hesitation between when I click on a window to drag it and it actually starts moving.  I'll click on the window and move the mouse, but it'll be a second or two before the window actually moves. It jumps to the mouse position, then starts moving as it should with the mouse.

Happens with or without Desktop Effects active, with both OpenGL and XRender composting and Native and Raster QT graphics system.

Thanks Martin, for the update.  This is a very annoying bug, and I'm not sure I'll keep my sanity having to live with it for two months.  I know with KDE apps, I can drag from just about anywhere in the window, but I use several non KDE apps throughout the day and drag them around the desktop and between monitors quiet often.  They have no way of dragging except via the title bar.  Is there a patch I can apply to something to fix this now?  I have no problem compiling whatever I need too to rid my system of this.

you maybe also want
https://git.reviewboard.kde.org/r/105801/

also it only affects the Aurorae deco, so you could change to oxygen etc. in the meantime (unless you compiled the patches in ;-)
Comment 4 lnxusr 2012-08-02 07:03:09 UTC
Ahh.. Thanks Thomas.  I missed the aurorae component in while reading bug 304249.  I'll save myself the time and possible headache of patching and compiling and just oxygen for a while.  Messes up the ascetics of my desktop, but it may be due for a change anyway.

> I'm not sure I'll keep my sanity having to live with it for two months
it's only one month till 4.9.1.

I just want to point out that this regression was introduced in January or 
February. It seems to me that a simple test during the beta phase might have 
found this bug, with the project neon kvm it's extremely easy to test the beta 
software even without installing a beta version.

I'm sorry that I introduced this regression, but I just don't move windows 
through titlebar. I normally use the window content (mostly closer to the 
mouse cursor) or just Alt+left click

KDE Techbase gives 4.9.1 tagged in one month, but release is scheduled for October 2.

True, a simple test of the beta would probably have found this, but I don't like to do betas on my desktop.  I have been toying with the idea of using a VM for this, but haven't gotten around to it.  I didn't know about project neon kvm, but will defiantly look into that.

> I'm sorry that I introduced this regression, 
No need to apologize, I'm not a CS, but I do dabble in programming as a hobby.  I fully understand how bugs can get by the developer, especially on large, complicated projects.  I am surprised, however, that it went so long without being reported.  I appear to be the only person on earth that moves windows around by clicking on the title bar.... ;)

I can confirm this bug too.
Just tried the patch - https://git.reviewboard.kde.org/r/105784/ and it fixes it.
