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 http://bugs.trinitydesktop.org/bugzilla/show_bug.cgi?id=1693
