Original GitHub issue: https://github.com/hrydgard/ppsspp/issues/55

I'm testing some of my personal homebrew on ppsspp.
First, and maybe only thing I notice on a basic game is that there is no screen clear...

Starting the game : http://image.noelshack.com/fichiers/2012/46/1353093175-capture-du-2012-11-16-20-08-22.png
After a while.. : http://image.noelshack.com/fichiers/2012/46/1353093175-capture-du-2012-11-16-20-08-09.png

This game uses my own graphics library : https://github.com/GeeckoDev/gLib2D/blob/master/glib2d.c#L292
I would like to fix this but I don't know where to start.

Linux 3.6.6 - Mesa 9.0 - Gnome 3.6.2

Play around with the code in /GPU and /GPU/GLES . I've seen a similar issue with cube.elf on MacOSX so there's something going on...

I've added in NativeApp.cpp in function NativeRender a glClear after glViewport to test. This has corrected problem with virtual key display refresh, and correct clean on a game load.

The game is supposed to clear the screen itself by drawing a rectangle, the emu shouldn't have to do it explicitly, so there's a real bug somewhere.

Try it now, I fixed an issue that had this effect on MacOSX for me.

I can confirm this is now fixed. Awesome, thank you!

Also: ppsspp is on the AUR, can you add it to the website? https://aur.archlinux.org/packages/ppsspp-git/
