Description sombragris 2004-03-30 14:59:53 UTC
Version:            (using KDE KDE 3.2.1)
Installed from:    Slackware Packages
OS:          Linux

Some of the window decorations provided with KDE 3.2.1 present an excessive lower margin with some apps. An example is the levelmeter of AlsaPlayer 0.99.x. This is not consistent, especially because there are other window decorations that use all the correct margins.

Here is the list of decorations that draw the windows correctly:
System ++

Here is the list of decorations that draw the windows incorrectly:

I have comparative screenshots and intend to attach them.

Please consider fixing this issue. Thanks for all your hard work.

This is a screenshot of the levelmeter window of AlsaPlayer 0.99x showing the
increased lower margin in the Redmond window decoration.

This is a screenshot of the AlsaPlayer 0.99x levelmeter using the Quartz window
decoration. This is the expected behavior.

Some styles can treat "Tool Windows" differently. Maybe the problem is related to 
that feature. I have never seen the problem though, since I don't have AlsaPlayer.
Can you try to increase the Window title font size to something large, like a 24pt,
and report the result? I am most familiar with the b2 code. Is the window resizable?


Comment 4 sombragris 2004-03-30 15:57:00 UTC
Hi Luciano, thanks for commenting. I did what you requested. I changed the window title font to Tahoma 24 Bold and I can report that in BII and Redmond the lower border is still incorrect. There is no change.

Comment 5 sombragris 2004-03-30 15:59:31 UTC
I forgot to answer your second question. The window is not resizable. The window menu (Alt + F3 in the KDE default scheme) grays out the Resize command and the resize pointers do not appear on mouseover on the window borders.

Luciano, here are my results:

I don't think it is an Alsaplayer problem because there was no such issue as far as I can remember in KDE versions 3.1x or lower. I remember clearly using alsaplayer with the KDE 1 and Redmond windecs (both of them affected by the bug) with no problem at all. Thus, it is highly likely that this is a KWin issue.

Those styles specify their minimum size larger than the window's size. At least for some of them the specified minimum size is unnecessarily large.
Comment 9 Thijs 2011-12-06 11:54:56 UTC
Styles are not what they were a 7 years ago ;)
