please check bug #243181 The Blur effect works fine on my box and the thumbnail doesn't got white at all. I don't know whether my bug is related to "Lanczos filter" or not. I will try to explain it more clearer. I think what the "Present windows" effects does is: 1, on startup, arrange all the windows throughout the screen, all but the next window will be darkened. 2, when choose an other window, the chosen will be highlighted and previous highlighted window will be darkened. 3, on exit, bring the chosen window to the front. On my case, all the colors are fine. Windows doesn't got over-highlighted nor over-darkened. My case is the step #2 is very slow, i.e., when you choose a different window, it take a relatively long time to finish the "highlight-darken" process. When the process finished, all seems fine. I hope I explained well above. Yes, this is related to the Lanczos filter While changing the highlighting the filter is active and causes the slowdown. So what can I do with this bug? :-/ > So what can I do with this bug? :-/
Blacklist the lanczos filter or wait till we fix it ;-)
Blacklist the Lanczos filter in kwinrc will fix the problem. Thanks! *** This bug has been marked as a duplicate of bug 243181 *** |
