Fix interface artifacts on Intel GPUs
This is a continuation of fix for T78307. Turns out instancing do not
work at all, so enforce single widget drawing on macOS and Intel GPU.
It was also reported that certain AMD and Mesa driver suffer from
similar issue, so disabled instancing for this configuration as well.
