I have attached it

Comment 4 Vlad Zahorodnii 2019-02-11 08:32:12 UTC

The Scale and the Glide effect usually don't go along quite well. Could you please disable either one of them and see if KWin still crashes?

Sometimes, I'm getting this notification after waking up: "Desktop effects were restarted due to a graphics reset"

Comment 7 techxgames 2019-02-15 10:43:14 UTC

Sorry I forgot to reply

Comment 8 Vlad Zahorodnii 2019-02-15 10:52:32 UTC

Graphics reset is unrelated. Wait, so KWin crashes even after disabling either Glide or Scale effect? Does the backtrace look the same?

Actually, KWin doesn't crash, or at the very least, no KCrash no Apport notification popped up when the graphics reset happened.

Comment 10 Vlad Zahorodnii 2019-02-15 15:43:02 UTC

Well, okay then. Seems like glide and scale effect didn't go along quite well. If you use 5.14 make sure that only one of them is enabled. In 5.15, it's not possible to enable both of them.

If the crash still happens in 5.15, please file a new bug report. :-)

Oh thank God! I was actually planning on submitting a wishlist that will prevent or warn users not to enable both effects.

Just gonna wait for it to land on Kubuntu.  Thanks!  I'll keep in touch
