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.
