[SOLVED] E6330/E6530 Intel HD4000 weird graphics while photos.app is converting

Recommended Posts

I hope someone can help me out.

 

As title says I have graphic glitches while photos.app converts imported videos/syncing photos from iCloud, but only on my internal display, the monitor I use as secondary display connected via HDMI, and while laptops internal display produces those graphic anomalies, the second display stays clean.

 

i have two configs e6530 and e6330, both have i7 3520m cpu with intel hd4000 graphics, with working qe/ci(if this matters). Or this is normal with these hd4000 graphics.

 

my USB ports/sata ports/brightness slider in display settings/audio working fine, except this thing.

 

+1: when I stut down/restart my latitude, the weird graphics comes out again on shutdown screen.

Hello, have you tried to downgrade the bios to the A12 version? .... You can test the e6530 and if you get a positive result you can do it on the e6330.

You wouldn't be using my patched DSDT from E6230 BIOS A19 by any chance? Because that will most definitely trigger artefacts at shutdown, but not otherwise. I would not recommend using that DSDT for anything other than the E6230.

I will upload it later.

 

I can tell that i used the install pack from the 10 step mini guide, for both the e6530 and e6330.

 

Based on Hervé’s post, i have tried to replace the dsdt to the appropriate from Jake Lo’s guide, and the result was black screen only after booting.

It seems that downgrading solved the issue! Thanks for it, however I downgraded to a11 instead of a12.

 

Thank to all! Thread can be closed.
