Windowed fullscreen apps left sided corruption

[Shane Fagan]

This is a bug that I presumed was known but after talking about it on reddit I went looking and couldn't find a report about it. To reproduce the bug:

1. Open either Steam, a game or google chrome
2. Open into fullscreen, if the corruption isn't there toggle fullscreen on and off a few times

You will see a bit of dead space on the left side beside the Unity sidebar, the corruption is just graphical so all the buttons still are in their old positions they just look like they are offset. As well as that all the content of the page or what ever is still in the same position so its very easy to miss click things obviously.

I made a video of the problem: https://www.youtube.com/watch?v=-wSb93MBCgI

Do you have display scaling set to a value other than 1.0?

[Shane Fagan (shanepatrickfagan)]

Nope stock Unity, reinstalled 13 days ago no non-default settings other than a different wallpaper.

[Shane Fagan (shanepatrickfagan)]

I just checked the scaling and it doesn't matter what happens with the scaling it still has the corruption. I tested with both smaller and larger scale and I made sure to fullscreen it again to make sure it did a redraw.

[Marc Deslauriers (mdeslaur)]

How are you making Chrome go full-screen like that?

If I maximize it, I still have the global menu at the top and the unity launcher on the left.
If I hit f11, I no longer have the tabs or the URL bar.

[Shane Fagan (shanepatrickfagan)]

Im dragging it to the top of the screen. I just recorded the 1 window rather than the entire desktop because I had it set to record windowed games. So yeah its just a regular maximise not f11.

[Shane Fagan (shanepatrickfagan)]

Here is the video with the entire desktop recorded. Also a little more context, its only when the app is maximized in windowed mode, it doesn't happen in any other situation. Its just windowed fullscreen.

[Stephen M. Webb (bregma)]

Marco, this looks like a bug in the decorations, could you take a look?

[Marc Deslauriers (mdeslaur)]

Oh! I see, sorry, I got confused as I thought the video was showing the whole desktop.

That really is a weird bug, and I can't reproduce it on my machines with the intel driver.

[Shane Fagan (shanepatrickfagan)]

Yeah it might be specific to fglrx. I removed fglrx just there and it didn't happen with the open source one. So I think its definitely a corner case.

[Marc Deslauriers (mdeslaur)]

Possibly related to bug 1390234

[Shane Fagan (shanepatrickfagan)]

Sounds like it

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

It definitely is an issue with the newest fglrx driver so he was wrong with the bit he said about it only affecting the repo version. Also the clarification has to be made it doesn't happen with every app its just games in windowed mode (it doesn't have to be maximized just windowed mode) and very particular maximized apps. So for me I noticed it in Steam and Google Chrome but like they said on that thread Blender too. So it should be slightly easier to figure out when you know exactly what apps are doing it I suppose.

[Shane Fagan (shanepatrickfagan)]

Just tested in 15.04 and its fixed completely. I don't know if it was fixed externally or you guys did it but id say you can mark it as fix released.
