Hi,
My setup is the following:
PC: HP T620 Plus with two AMD graphics card Monitors: 3 Dell 4k Monitos running at 1920x1080. Two are attached to the primary card and one to the secondary card.
When moving the mouse inside a window (firefox, xterm, ...) on a rotated screen on it is very slow. Moving the mouse outside a windows on the background is fast as it should be. The mouse also disappears when it is not moving.
The following versions were used: Xorg-1.17.2 xf86-video-ati latest git version (ce9914a) mesa-11.0.0 libdrm-2.4.64 libLLVM-3.7
It does not matter if using DRI2 or DRI3. It does not matter if ColorTiling2D is on or off.
Kind regards Jan Burgmeier
