--- Comment #3 from Matthias Dahl <ua_bugz_...@binary-island.eu> --- I can confirm this issue as well. It has been long-standing, unfortunately. I will attach two more screenshots which show it rather prominently -- one from the application launcher and one from the desktop effects kcm. My experience is that this can only be triggered when scrolled via mouse wheel and that way it is 100% reproducible and happens all the time. For example: 1) Open the desktop effects kcm. 2) Scroll the list of effects one wheel unit down --> Font corruption happens If you scroll another wheel unit, everything looks fine again. Another wheel unit, and the font is garbled again. And so forth. I have tried to narrow this down but so far have failed. If there is anything I can do at all to help track this bug down, please let me know. I am seeing this on a fresh Gentoo x86_64 system w/ frameworks 5.25.0, plasma 5.7.4, Qt 5.6.1 and freetype 2.6.5. Xorg uses nvidia driver 370.23. KWIN Compositor is using OpenGL 3.1. But neither of those latter ones make any difference. -- You are receiving this mail because: You are watching all bug changes.
