--- Comment #13 from wrongfix <[email protected]> --- still happens in 6.6.5 Recently I triggered this bug as: 1) close X2go session, while having other window in focus. 2) the X2go session manager window become gray (not resposive), focus still on other window 3) the Xwayland start to consume 100% cpu Here is back trace of Xwayland process: Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". 0x0000561e30b034bc in ??

Expected behaviour --> it should be possible to close non-responding window in normal way. It is an issue in kwin xwayland implementation. -- You are receiving this mail because: You are watching all bug changes.
