Version: (using KDE 4.1.2) OS: Linux Installed from: Unlisted Binary Package Resizing windows with the "Show window contents while resizing" option disabled, and with compositing/effects enabled, causes bits of the rubber-band outline frame to draw incorrectly, and bits of it to be left behind. I tried to capture video, but all desktop video recorders stop when resizing windows :) Machine is running Arch Linux, KDE 4.1.3 (Qt 4.4.3) with KWin 3.0. X.Org X Server 1.5.2 on Intel 915.
Created attachment 28365 [details] Photo of desktop showing some of the behaviour I managed to grab a photo which shows part of the problem, with an extra outline band left during the resize.
I can confirm this under 4.5.2, Kubuntu 10.10. NVIDIA driver 260.19.06, GeForce 9500 GT.
this happens only if the resized window hasn't been active before yesno? consider to try the resize effect which will resize w/o updating the window contents but scale the window texture instead (when compositing is suspended you should get the normal outline)
(In reply to comment #3) > this happens only if the resized window hasn't been active before yesno? No it happens also when the window has been active before. To clarify, the strangely drawn rubber-band outline and artifacts do only show up during the resizing itself. When resizing is finished they vanish.
With Compositing enabled the Resize Effect is used instead of the outline. This "fixes" the issue.
