Slow first draw image with Skia/EGL

[MuseRay]

Hi all,

I'm developing a UI framework using Skia for rendering and encountering a specific performance issue: ​The first draw of control images (e.g. button icons) is significantly slower​ than subsequent draws when using EGL backend. even though I've pre-processed the image with SkImages::TextureFromImage.

Profiling shows the bottleneck occurs specifically in ​**GrDirectContext::flush()**​ during the first draw operation. 

​I've also tested with the ​WGL GPU backend​ (on Windows) using the ​same​ code flow, and ​did NOT observe the performance drop on the first draw. The initial GrDirectContext::flush() latency was normal (close to the latency of subsequent flushes).

Thanks for any insights!
