I just did a major Yocto upgrade from "daisy" to "thud" branch, and I noticed that some characters/glyphs happen to be slightly corrupt. The problem occurs randomly, but when a corrupted character is rendered multiple times on the screen, all of its instances are corrupted the same way. It looks like this: https://ibb.co/LYP4JCx I tried using various QT environment variables, but the only one that worked was QT_QUICK_BACKEND=software. However, this led to a very significant slowdown, so it's not an option. I'm not using X11 or wayland. I'm not modifying the graphics drivers or the QT layer in any way. Following are Qt environment variables on target: export QT_QPA_EGLFS_INTEGRATION=none export QT_QUICK_CONTROLS_1_STYLE=Flat export QT_QPA_EGLFS_NO_LIBINPUT=1 Has anyone experienced similar problem? Is there any configuration detail I might be missing? Regards, Ankur ________________________________ This email is confidential and may contain information subject to legal privilege.
