Hello everyone,
I hope this is the right place to find a little bit of help... I have a Gentoo machine with KDE 5 Plasma. It has been running for a few weeks, now, and I did not have problems until I restarted my computer today. Controls started blurring making texts unreadable (see picture: https://i.imgur.com/Lg15o5d.png ). When hovering with my mouse, the text unblurs for a second, then blurs again (smoothly animated). Also holding a window and moving it around keeps the window and all controls inside unblurred. This effect only appears when I set the compositor to OpenGL. Changing to XRender is a workaround, but I'd like to fix the OpenGL settings. How can I fix my KDE installation? Some version information: Kernel: 4.3.4-gentoo Gaphics Card: NVIDIA GTX 970 using nvidia-drivers-358.16-r1 KDE: Plasma 5.5.4 KDE Framework: 5.18.0 If you need more versions, settings, logs or USE flags, please just tell me what you need and I will happily provide it. |

any recent upgrades?
couple things to try 1) test as a new user 2) rename your kwinrc file in ~/.kde[4]/share/config/ and restart kwin
3) assuming you compile you own Nvidia drives recompile them ps - no real idea, these are just something I would try |

Run "nvidia-settings" and disable FXAA.
FXAA is a shader based full screen anitaliaser which causes exactly this. Unfortunately, there's no environment to control this (so we cannot downforce it from kwin) - if you want to use it in some game, rather invoke that as
You may also be able to disable it for kwin_x11 in nvidia-settings with an application profile. |

@google01103: Thank you for the ideas. I am a lazy guy, so I just skipped to the most simple solution with the setting....
Simple and effective! Seems like I enabled it at some point and it just took effect after the reboot. Thanks a lot! |

Same issue, text is undreadable and is like "beating", that is, each second seems to be "detailed" and gradually it becomes "fuzzy" and same each 1 second. While moving mouse over buttons than change any property (color, shadow, etc) it changes more quickly. But it's really a headache try to work this way. It doesn't happen if I login like root, but with my user (that have configurations from other OpenSUSE-Plasma previous versions) and just after install NVidia drivers from their repositories.
Change FXAA and reboot does nothing in my case. Even when trying to take a screenshot, while resizing area to capture, blurry effect changes. Operating System: openSUSE Tumbleweed 20211016 KDE Plasma Version: 5.23.0 KDE Frameworks Version: 5.86.0 Qt Version: 5.15.2 Kernel Version: 5.14.11-1-default (64-bit) Graphics Platform: X11 Processors: 8 × Intel® Core™ i7-9700K CPU @ 3.60GHz Memory: 15.4 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 2060/PCIe/SSE2 https://imgur.com/dIPrOiZ |

Tried with a new user? Might help in deciding to clean up previous configurations, as suggested in the very first answer to the original post...
Running Kubuntu 22.10 with Plasma 5.26.3, Frameworks 5.100.0, Qt 5.15.6, kernel 5.19.0-23 on Ryzen 5 4600H, AMD Renoir, X11
FWIW: it's always useful to state the exact Plasma version (+ distribution) when asking questions, makes it easier to help ... |
