Letterbox horizontal shift problems with vblank_mode=xpresent

Hey there,

due to problems with the xfwm blanking mode on my amdgpu laptop, I recently switched to xpresent.

Now, as soon as I apply a non-native display resolution to xfwm, it causes some rendering problems which makes the entire desktop merely unusable until I switch it back to a FullHD native non-letterboxed screen resolution.

I switched the blanking mode back to default (which might be glx or so) - then, non-native resolutions work again, whereas there still is this ugly framebuffer shifting/artifacting.

Could you recommend me anything to do?
Should I file a bug somewhere?

Thank you in advance!

The bug tracker would be the place to file the report.
