--- Comment #8 from Dmitry Kazakov <dimul...@gmail.com> ---
Git commit 0ea1676c0d786e2da71b080e9a5e3efe04086962 by Dmitry Kazakov.
Committed on 08/06/2022 at 08:03.
Pushed by dkazakov into branch 'krita/5.1'.
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.
