framebuffer geometry changed between kernel 4.5.0-1 and 4.5.0-2
Hi
Up until kernel 4.5.0-1 my console had the following geometry:
]$ fbset -i
mode "1920x1200"
geometry 1920 1200 1920 1200 32
timings 0 0 0 0 0 0 0
accel true
rgba 8/16,8/8,8/0,0/0
endmode
Frame buffer device information:
Name : radeondrmfb
Address : 0xd0475000
Size : 9216000
Type : PACKED PIXELS
Visual : TRUECOLOR
XPanStep : 1
YPanStep : 1
YWrapStep : 0
LineLength : 7680
Accelerator : No
Since kernel 4.5.0-2 it changed to this:
]$ fbset -i
mode "1024x768"
geometry 1024 768 1920 1200 32
timings 0 0 0 0 0 0 0
accel true
rgba 8/16,8/8,8/0,0/0
endmode
Frame buffer device information:
Name : radeondrmfb
Address : 0xd0475000
Size : 9216000
Type : PACKED PIXELS
Visual : TRUECOLOR
XPanStep : 1
YPanStep : 1
YWrapStep : 0
LineLength : 7680
Accelerator : No
So the resolution is 1920x1200 but the console fills up only 1024x768
in the upper-left part. In addition, my display manager (sddm) seems
to "inherit" this 1024x768 resolution as its own. At least it looks
like it, it fills up the whole screen and all the ui elements are bigger
than before. It goes back to normal, i.e., 1920x1200 when I log in and
KDE loads up.
My graphic card is:

I booted with debug, grepped for "drm|console|radeon|fbcon" and I noticed
the following changes:

Is there any way to fix it?
