Filed from caserun https://tcms.engineering.redhat.com/run/99313/#caserun_3816195 Version-Release number of selected component (if applicable): RHEL-7.0-20131111.1Build : RHEL-7.0-20131111.1 xorg-x11-server-Xorg-1.14.99.901-5.20131101.el7.x86_64 xorg-x11-drv-ati-7.2.0-6.20131023gitf1dc677.el7.x86_64 kernel-3.10.0-48.el7.x86_64 Steps to Reproduce: Get your display highest supported resolution, use xrandr for example (it is the first resolution in the list, 1650x1050 in my case). 1. Run xrandr and set higher resolution that you have supported xrandr --output LVDS --panning 1600x1200 Note: replace "LVDS" with real name of your output interface. Actual results: Panning works fine but when returning to native res there is severe screen corruption. Panning and un-panning again (by feel) just makes it worse.. Expected results: Make sure the screen is panned and you can tavel in panned space. No crashes/ errors at display should appear.
You need linux-firmware >= 20131106-0.1.git7d0c7a8
This need to be retested but here i can not reproduce with : linux-firmware-20140102-0.2.git52d77db.el7.noarch kernel-3.10.0-89 mesa-dri-drivers-9.2.5 xorg-x11-drv-ati-7.2.0-8.20140113git3213df1 xorg-x11-glamor-0.5.1-4.20140115gitfb4d046c
We believe this is already fixed but moving to 7.1
This should already work in 7.0 but reassigning to kernel as if it is an issue than it is a kernel issue.
Verified fixed in: RHEL-7.2-20150820.0 xorg-x11-server-Xorg-1.17.2-7.el7.x86_64 xorg-x11-drv-ati-7.5.0-3.el7.x86_64 kernel-3.10.0-306.0.1.el7.x86_64 linux-firmware-20150727-41.git75cc3ef.el7.noarch mesa-dri-drivers-10.6.0-1.20150616.el7.x86_64
