--- Comment #21 from Bernd Steinhauser <li...@bernd-steinhauser.de> --- Sorry, can't do that, I'm not running team viewer. I did another test though. I ran konsole inside of urxvt and tried a few things. On normal splitting, there are no error messages, but as soon as I mix vertical and horizontal splitting, I get about 100 of these messages: qt.qpa.xcb: QXcbConnection: XCB error: 8 (BadMatch), sequence: 5129, resource id: 35651610, major code: 130 (Unknown), minor code: 3 That gave me an idea that it might actually be related to kwin or how konsole interacts with kwin (since iirc kwin handles the xcb connections). So as a wild guess, I tried it with the compositor disabled and then it worked! So to sum up: compositor activated -> bugged compositor deactivated -> works Weird, isn't it? Doesn't matter which backend for the compositor is used, I tried all of them (normally, I'm using the OpenGL 3.1 backend). Also played around with the desktop effects and other compositor-related stuff, but couldn't find any further influence. -- You are receiving this mail because: You are watching all bug changes.
