Primusrun issue on nvidia optimus laptop on Linux

[GoogleCodeExporter]

Describe your system:
 - Operating System (be specific): Linux Mint 16
 - Machine type (32-bit or 64-bit): 64
 - Mupen64Plus version: the newest
 - Plugins used: tried with all

For visual artifacts, give:
 - flashing, flickering

Describe the problem:
Anytime I run mupen64plus with primusrun I experience flashing, flickering.

Bumblebee and nvidia are correctly installed, everything works, steam games 
etc. so the problem must be with mupen64plus

Mupen64plus is from trusted source -

I personally have no similar system (dual gpu) and thus cannot reproduce it. It 
also doesnt happen with pure intel igp and nvidia gpu systems. 

Can you make a list of the plugin combination that you have used and what 
different symptoms you've experienced with each combination? This could really 
help someone with a similar system to reproduce the problem. Also your 
mupen64plus.cfg and the exact versions would be nice. Because the versions you 
are using right now will not be the newest in  6months. You can get the 
versions from dpkg by requesting them through 'dpkg -l'. But it is good that 
you told us the source of the installed packages so we know were to look for 
the used patches

Are drivers and primusrun the ones provided by Linux Mint 16? Did you modify 
them or the kernel?

And a list of tested roms (the shown md5 sums are very important) would also be 
very useful

And just for me personal: why is this ppa a trusted source? Also malware can 
easily be uploaded to an PPA

The newest drivers from xorg-edgers, including nvidia 331.20 and the kernel 
from http://kernel.ubuntu.com/~kernel-ppa/mainline/ - version v3.12.5-trusty
That ppa was recommended here 
https://code.google.com/p/mupen64plus/wiki/DistributionPackages

I switched to mupen64plus from ubuntu repository and the same issues.

The attached config doesn't look like you've ever used any other gfx plugin 
than mupen64plus-video-rice. Please add the requested information about what 
other plugin combination you've used and what problem you noticed with it.

If it only happens with mupen64plus-video-rice then you can change 
ScreenUpdateSetting in [Video-Rice] to 2 or a different value mentioned in the 
comment above it.

Changing ScreenUpdateSetting to different value fixed all the issues. Thanks!

Just as hint: The PPA you've mentioned earlier is my own PPA

Just an explanation why I close this bug:  The problem seems to be that your 
bumblebee/"dma sharing driver" is not preserving the content of the previous 
rendering in the buffer. This is required to avoid flickering with rice and the 
ScreenUpdateSetting=1. The flickering is nothing "unexpected" when the this 
precondition for ScreenUpdateSetting=1 is not fulfilled
