In plasma5, when resuming from suspend, kwin breaks and even though the screen is locked, I can still see data that was present on the screen before it was locked. Reproducible: Always
*** Bug 344934 has been marked as a duplicate of this bug. ***
can you please describe in more detail what you experience, especially what you mean with "kwin breaks"?
I start seeing graphical garbage on the screen. Rapidly flickering and distorted. It happens sometimes when resuming from suspend
Please don't change back to critical. We still don't have enough information to understand the issue and if you change to critical our release manager will yell at us ;-) Can you please provide the following: * a foto of the issue * output of qdbus org.kde.KWin /KWin supportInformation
Is a security hole that bypasses the screenlocker really not important?
And I can't upload an image. the bug tracker says its 4.2MB and it only wants less than 4 in size
(In reply to illumilore from comment #5) > Is a security hole that bypasses the screenlocker really not important? we do not know that yet. So far all we have is a graphical distortion. That you can bypass the lock screen is new to that bug report. > And I can't upload an image. the bug tracker says its 4.2MB and it only wants less than 4 in size Feel free to put it on an image hoster.
"That you can bypass the lock screen is new to that bug report." I clearly mention that in the title and the summary that it shows data that was on screen before the screen locked.
