189292 2009-04-10 17:45:32 +0000 Minimize task bar entry is not working properly with compositing enabled 2009-04-13 12:17:37 +0000 1 1 4 Plasma kwin general unspecified Gentoo Packages Linux RESOLVED DUPLICATE 189435 NOR normal --- 0 alecm kwin-bugs-null carlvanopstal 0 oldest_to_newest 741397 0 alecm 2009-04-10 17:45:32 +0000 Version: (using KDE 4.2.1) Compiler: gcc (Gentoo 4.3.3-r2 p1.1, pie-10.1.5) 4.3.3 OS: Linux Installed from: Gentoo Packages This is probably the cause of Bug 188987: To Reproduce: 1. With compositing enabled, minimize a window. 2. Right-click on the taskbar entry (notice that "Minimize" is not checked) 3. Click on minimize (should restore but nothing happens) If compositing is disabled, everything works as expected. 741414 1 mgraesslin 2009-04-10 18:19:10 +0000 I cannot reproduce. In step 2 "Minimize" is checked. What is your setting in systemsettings -> desktop -> desktop effects -> advanced for thumbnails? Never, for shown windows or always? 741418 2 carlvanopstal 2009-04-10 18:28:43 +0000 Yes, I filed bug 188987, and Alec has hit the nail on the head. I checked and have the same issue, with 'Keep windows thumbnails' set to 'Always' Setting it to 'Only for shown windows' solves the 'minimize' issue, and (therefore) also the krdc issue (bug 188987). Big thanks for some splendid investigation! 741491 3 alecm 2009-04-10 21:40:12 +0000 Martin, Yes, I have "Keep window thumbnails" set to "Always." So is it a known bug, then? 741510 4 mgraesslin 2009-04-10 22:33:20 +0000 Well there is another bug caused by this: #181848 I'm not sure if this bug is a duplicate of it. 742385 5 mgraesslin 2009-04-12 23:23:09 +0000 *** Bug 188987 has been marked as a duplicate of this bug. *** 742532 6 mgraesslin 2009-04-13 12:17:37 +0000 *** This bug has been marked as a duplicate of bug 189435 ***
