Created attachment 723 [details] Screenshot showing the missing icons On the latest Raspberry Pi OS (full) (from 2021-01-11) I installed pulseview on a Raspberry Pi 4 2GB by compiling all components manually. Some of the icons in pulseview are not showing up, as visible in the screenshot. The following icons are affected: - new session - open file - save file I installed all dependencies as in the documentation I notice that all the affected icons are pngs. On startup I get the following message: ' qt5ct: using qt5ct plugin palette support is disabled libpng warning: iCCP: known incorrect sRGB profile ' The libpng version is 1.6.36. On another linux system (not raspberry) with the same libpng version all icons show up. I searched the buglist but did not find any related bug
