Incorrect font rendering within Qt5 Embedded
Found incorrect font rendering with Qt 5.13 Embedded. Linux version - 5.2-rc1, device - NanoPi A64. In most cases invalid background is visible behind text.
Here is qt5 log: https://pastebin.com/wAsmVfha
In the log I found a suspicious line which might be related to the problem:
gpir: unsupported nir_op: b2f
