https://bugs.kde.org/show_bug.cgi?id=384660 --- Comment #3 from Martin Flöser --- Is the hardware the same except for the graphics card? If yes I strongly suggest to do a test of the hardware. What you experience is not normal. It might be driver specific, but that we see such distortions across different drivers is not normal. I have never seen any reports like yours. This indicates to me that there is a problem with your setup - either a general problem with the underlying Linux system or with hardware. Given the look it might be a memory issue. -- You are receiving this mail because: You are watching all bug changes.

Is there something i can do to (apart changing motherboard!) to debug the issue? thanks... -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=384660 --- Comment #5 from Antonio Orefice --- Hi again Martin, i just saw the following: https://bugs.kde.org/show_bug.cgi?id=361154 In particular here: > Opening new Windows causes alternate monitor (dual-monitor setup) to flicker > rapidly I'm observing the very same, and my window decorations are corrupted as well: https://youtu.be/e3BH4nEq2S0 See that the corruption is in the shadow area and the decoration area. Also, i think it is important, the decoration corruption starts togheter with the "flashing/flickering". Are we sure this is not somehow related with the afromentioned 361154? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=384660 --- Comment #6 from Antonio Orefice --- I again, in the process of isolating the problem, i reated a new user and was unable to reproduce my issue, so i tried to replicate one by one the "standard" plasma setup on the main user. I found that switching my decoration from oxygen (with customized settings) to breeze decoration makes the issue magically disappears. I'm running it from an hour and an half and i've yet to seen a corruption or a flicker, where in the past i boserver them even 5 to ten minutes after restarting kwin_x11. In my first post, i wrote that: > *Change decoration style was not sufficient to make the issue goes away, that is half-true. >From my testing it seems (finger crossed) that if i start kwin_x11 with the breeze decoration already set, then no corruption flicker occours, while switching decoration after the flickers starts to kick in, and without restarting kwin_x11 process, is useless. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=384660 --- Comment #8 from Antonio Orefice --- I'll probably update you by monday, as i can test only in business days. I plan to keep using breeze another day, and, if no flicker occurred, i'll change it to oxygen without restarting the kwin_x11 process; if no flicker will occour, i'll try to switch to oxygen after restarting kwin.

https://bugs.kde.org/show_bug.cgi?id=384660 --- Comment #10 from Antonio Orefice --- I found a way to reproduce the issue; made a script for that (attached: flicker.sh). For it to work on my system, i've found that the following conditions have to be met: Use Oxygen Decoration Use "Active window glow" Disabling "Active window glow" or switching to another decoration makes impossible to reproduce. After the script has finished, it will tell you to maximize/restore the last opened window. >From my tests, the operation will cause flickering and/or decoration corruption, depending if i'm running single or dual head setup. could it be that the patch applied to fix 361154 just fixed the shadows, but not the glow? Just shooting in the dark.

https://bugs.kde.org/show_bug.cgi?id=384660 --- Comment #14 from Antonio Orefice --- Unfortunately, after several hours of use, the problem appeared even without glow; this time it happened using intel driver (in the past i tried nvidia proprietary on a gtx1050ti and modesetting driver on haswell= Another hint, is that since i've even changed back from modesetting driver to intel one, the script posted earlier does not reproduces the error anymore.

Just added this patch to my local patchset, seems to work so far - no flickering, even after opening several mpv instances and a few games! -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=384660 --- Comment #21 from triffid.hun...@gmail.com --- After more extensive experimentation, this certainly makes it a lot more difficult to trigger the underlying bug (my previously reliable trigger methods failed at first) but doesn't prevent it completely.
