Unity desktop misbehaves with applications that use direct rendering with the FGLRX driver

[Maxim Therrien]

I've been using Ubuntu 14.10 for a while now, and I ended up switching to the FGLRX driver for performance reasons. My laptop is an Acer Aspire 5742G-7353 with an ATI Mobility Radeon HD 5470 video chip on it. I have noticed that some applications (So far, I've only seen Blender and Chromium do this) displays a little bit (maybe 10-20 pixels?) to the right when maximized. The drivers that are available from the ATI website worked fine, but I had to use the version from the repos since it no longer works with 14.10. Problem only exists in the repo version.

Edit: I have switched to KDE and seen it happen in Blender with kwin compositing on. The bug disappeared immediately after disabling compositing.

Status changed to 'Confirmed' because the bug affects multiple users.

[Paulo Narciso (p-narciso)]

I woul like to update this issue to say that this problem still happens with the latest Catalyst 14.12.

[Marcin Jakubowski (mjakubowski)]

Also happens with Google Chrome. If the application starts in maximized mode, it will render its contents fine, until demaximized and maximized again.

[Marko (markotheprogrammer)]

Also happens with Opera and it happened to me with vlc(fullscreen).

[iBART (mogio)]

Confirmed, with Chrome, Chrome Beta and Chromium but if I disable the hardware acceleration this bug disappears.

[vinod777 (vinod777)]

This bug appears for Chrome, Chromium, Adobe brackets(node-webkit based app), Opera browser.
When disable hw acceleration in Opera, this bug disappears for Opera.

I also found that when an app is offsetted, toggling "Snapping Windows" in Compiz will make the app display correctly. Completely enabling/disabling wont work forever, you need to toggle it when an app is in offsetted state.

Ubuntu 14.10 fresh install
Tried with AMD drivers from AMD site and fglrx-updates from ubuntu repo. Not fixed.

[Marko (markotheprogrammer)]

This seems to have been fixed with catalyst 15.3 driver(currently its not available for download for linux unless you are using Ubuntu 15.04, Canonical always gets amd driver first).
