Git commit a9b46a6d156a63484f48c365e3894f8d385259d5 by Dmitry Kazakov.
Committed on 08/06/2022 at 07:58.
Pushed by dkazakov into branch 'master'.
Explicitly disable texture buffers on ANGLE renderer
Angle has suboptimal implementation of texture buffers. It does a
long chain of copy operations just to upload the buffer into a
texture:
source user data -> ram buffer -> staging buffer -> native buffer -> texture
It makes painting with huge brushes really slow.
