3D view/context invisible when hitting "Play" (< 1.7.24)

[Pendrokar]

All objects in the scene get deleted when hitting Play. After pressing Play again to stop, then the scene is empty and has to be reloaded.

On startup both the scene panel AND the game panel have a 3d context.

However when you press the play button, the 3d context in the game panel dissapears and Unity responds with the error

width <= 0 || height <= 0 UnityEditor.DockArea:OnGUI()

Fixed in Wine 1.7.24.

It seems this bug occurs due to a missing directory, creating the directory with the following path fixes the issue:

mkdir -p $WINEPREFIX/drive_c/users/$USER/AppData/LocalLow

WINEPREFIX environment variable should be the path to your Unity wineprefix('$ export WINEPREFIX=').

If this bug occured even by using installation scripts found in this git repository, then it should be reported, as the script should have created the directory.

[Pendrokar]

A patch has been created by a Wine developer. http://bugs.winehq.org/show_bug.cgi?id=22896#c15

This bug is still not marked fixed in 1.7.23. Requires testing so it would be added in the next development version of Wine.

This is so cool. I'll update the script to test whether the current Wine version has the bug or not.

[Pendrokar]

What do you mean by "current Wine version", development or the one of git(master/nightly)?

[jurf]

@Pendrokar please test the script, I don't have enough space or resources to do so myself and I'm not comfortable with letting an untested script into the wild.

[Pendrokar]

Seems fixed on an entirely clean install(no ie8 or tahoma).

Sorry Jellyface, but the verb script uses winetricks and I have had trouble making it use a patched Wine. Lets test it when 1.7.24 or 1.8 comes out.

[jurf]

Strange, I had to install Tahoma.

Protip, if you want Winetricks to use another Wine, assign the $WINE variable to it. Also, it does not matter what you install it with, as long as the install was successful, it cheanges the prefix appropriately, trust me, I do it all the time.

And if you have a patched Wine, you probably have a normal Wine too, right? Could you test it at least there, since that's the Wine we are supposed to be supporting, to see if it installs everything correctly.

Thanks.

[Pendrokar]

In order to test this 'Play' issue, I did not need Tahoma, I was somehow able to create a cube GameObject to test the functionality.

Very well, since this script is the latest I will test it with Wine 1.7.22

[Pendrokar]

Yes it works, even the workaround conditions, good job. Though I should have used the latest Unity. Oh well...

[Pendrokar]

Fixed in Wine 1.7.24. Though Ubuntu is falling behind on binary versions, as 1.7.22 is the latest available.
