After updating wlroots to contain renderer v6 patches, screenshots taken on my vertical monitor are rotated 180 degrees.

Screenshot

image

My output config is

output DP-2 pos 1440 530 res 3840x2160 scale 1.5
output DP-1 pos 0 0 res 2560x1440 transform 270

(The vertical monitor is DP-1.)

I'm running

$ uname -a                                                                                                                        
Linux lynwood 5.8.0-0.bpo.2-amd64 #1 SMP Debian 5.8.10-1~bpo10+1 (2020-09-26) x86_64 GNU/Linux

with amdgpu on an RX 580.

TBH that sounds like a grim bug. When i hack the wlroots example to capture the raw buffer for my 90-degree rotated output, I see the buffer rotated counter-clockwise. In other words, if I look at my monitor and tilt my head so that the brand of the monitor appears in the natural orientation, then I see exactly what the screenshot shows.

Fix 180-degree rotated buffers without Y_INVERT
8bba5b6 
When the compositor sends a buffer without the Y_INVERT flag, the
resulting image had it rotated by 180 degrees.
