Tim, Darrell,
I recall discussion earlier about optimizations applied to R14. Did any
of those have to do with the number of times a toolbar or menu is drawn or
refreshed on first display? I ask because I am seeing a lot of text that is
either missing or cut-off when a kcontrol app, or menu is displayed.
The text headings in the individual kcontrol apps and pop-up config items
are the worst. When you first open a config applet the top-half of the text
is for the block titles. For example:
open 'konqueror --profile filemanagement' (or 'Personal Files' on
taskbar)
The first block of options contains radio buttons for 'color' or
'picture'
the block title for that group is 'Background'. When that dialog is first
displayed, the top part of 'Background' is missing like it got clipped when
the next element was drawn -- and then was never refreshed a last time to
insure the entirety of all elements were visible. I don't ever recall
seeing this behavior in the past and comparing to an older 3.5.13-sru
install -- that does not occur.
Another area is menu entries. Open kwrite and open the 'Edit' menu. When
I first to this the Ctrl+G 'Go To' line contains nothing but the underscore
and the Ctrl+G tooltip:
" _ Ctrl+G "
I just clicked it again and this time the "Overwrite Mode" text
disappeared leaving only the 'Insert' tooltip on the right-side. An time
focus changes, the text is restored (both in kwrite, kcontrol, etc..) Since
a focus change (which I guess forces a redraw) corrects the issue, it makes
it almost impossible to capture with ksnapshot.
I have nothing concrete, but the feel I get is that some type of
optimization fix was done to prevent TDE from redrawing a menu or applet
one or two more times after initial display. I don't know if that is it,
but it just feels like the elements are 1 redraw or refresh away from being
ready when they are first displayed.
You guys think about this and let me know where to go with it...
After updating from 3.5.13.2 to R14.0.0 (nightly-builds) I also noticing some
problems in rendering. See bug
