Diagonal tearing in OpenGL output on Aruba r600 GPU (Radeon HD 7660D) since Linux 5.16
I have a Radeon HD 7660D GPU and for some time I observe diagonal tearing when playing a video using OpenGL (e.g. with "mpv --video=gpu"). Other displaying methods (Xv, VDPAU, plain X11) are not affected. It happens in current Linux 5.17.2, 5.17.1, 5.17.0 and I have been experiencing it for a few months.
Today I bisected it to v5.15-rc1-369-g0597ca7b43e4:
