Created attachment 135150 [details] configuration files, logs, and image of corruption Rotating a monitor causes screen corruption in ATI video driver version 23.0. Version 19.0 Works fine. (These correspond to CentOS 7.1708--latest--and .1611 (one earlier). Same version seems to work fine on RV730 (HD4650). To reproduce: Install CentOS 7.1708 server with gui with one user (X.Org video driver 23.0, XInput driver 24.1, Server Extension 10.0, glx 1.19.3, ABI 10.). Rotate monitor after logging in. Likely could reproduce with Live CD, but haven't tried it. CentOS 7.1611 (video driver 19.0, XInput driver 21.0, server extension 9.0, ABI 9.0) works fine Xorg.0.log, lspcid, dmesg with drm.debug=14 log_buf_len=16M, xrandr output, gdm monitors.xml configuration, and image of corrupted screen attached
radeon_drv.so is from an upstream 7.6.99 development snapshot, which is at least 1.5 years old. Most likely this issue is fixed in the current upstream code. Please only reopen if it still happens with the xf86-video-ati 7.10.0 release or newer.
