Corrupt mouse cursor when using multiple monitors

[Heikki Berg]

I have two screens, and sometimes on one of the screens mouse cursor gets corrupted. So far always vertically in 5 slices. The corrupt cursor is always in the primary screen. The cursor is fine on the second screen. If I take a screenshot (using the screenshot application on Linuxmint) cursor looks normal on the screenshot. At the same time it is corrupt on the screen. So some layer between the buffer from where screenshot is captured to displaying the image on the screen corrupts the cursor.

Corrupt cursor needs that AMD fglrx/Catalyst drivers are installed. I have now the latest 14.1 beta installed, but I had the same with previous beta.

Reboot fixes the problem, until after a while it happens again.

I have verified the problem with fresh installs of Kubuntu 13.10, Linuxmint 16 KDE and Linuxming 16 Cinnamon. Now system is running Linuxmint 16 Cinnamon.

For the first time, the corruption is now in both screens simultaneously.

[Heikki Berg (heikki-berg)]

Video and photos of the thing. Screen and video capture shows perfect pointer. However on the screen pointer is corrupt.
Simultaneous screen capture and video (with camera) provided. Does this isolate the bug at all?

As this occurs under multiple window managers, it suggests the problem is either under xorg or fglrx - does it happen with the open source driver? If not, I think it'd be worth reporting this to AMD

[Heikki Berg (heikki-berg)]

I have reported this through http://www.amd.com/betareport at the same time as this bugreport.
In that bug report I refer directly to this bugreport as well.

Unfortunately, AMD bugreports are like shouting in the void. I do not know whether the report has been registered and I can not follow the issued bugreport.

[Heikki Berg (heikki-berg)]

I have used only SW driver (fresh install) or AMD/Catalyst driver. No mouse pointer corruption in a fresh install until AMD/Catalyst drivers are installed.

[Kazriko (kaz-lpad)]

Until recently, I can't actually remember a time in my entire history of using AMD cards with Linux and fglrx that I didn't have cursor corruption on one of the screens. Oddly, my 7750 at work with Mint 17 with 3 screens hasn't exhibited these symptoms yet, but I'm definitely getting the same thing on Ubuntu 14.04 with an A10-7870K with 2 screens.

One thing I've observed in that the screen with the corruption actually stops changing the cursor entirely. You can move over elements where the screen would normally change to another cursor shape, and the cursor will jump a little as if moving where the active position in the cursor is, but will remain the same part of the original cursor repeated.

Same thing happens to me on Ubuntu GNOME 15.10 x64 with fglrx 2:15.201-0ubuntu2~15.10.2. Anyway we can bump this report to fglrx instead of linuxmint directly?

[Stephen Ranger (stephen-w-ranger)]

I added fglrx-installer and fglrx-installer-updates. It would be nice to get this fixed as it's a longstanding bug in the driver that I believe the official AMD Windows driver fixed a while ago.

[penalvch (penalvch)]

Stephen Ranger, it will help immensely if you filed a new report with Ubuntu by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information running the following from a terminal:
ubuntu-bug xorg
