Da due settimane vedo un incremento dei problemi di rendering grafico dispari sul mio MacBook Pro (13 pollici, metà 2012). Questi problemi includono sfarfallio, figure dalla forma strana, rumore grafico e altre cose fastidiose.
I problemi grafici si verificano sia sul display LCD sia sul display esterno. L'evento è per lo più casuale, ma tende ad accadere leggermente di più sul mio display LCD.
Esempio di problemi di rendering grafico
Ho i seguenti grafici / display (ho usato system_profiler SPDisplaysDataType per il dump):
Graphics/Displays:
Intel HD Graphics 4000:
Chipset Model: Intel HD Graphics 4000
Type: GPU

Uso una porta Mini-display per l'adattatore VGA per il mio display esterno.
Ho le seguenti specifiche:
- Processore: Intel Core i5 a 2,5 GHz
- Memoria: 4 GB 1600 MHz DDR3
- Disco: SSD Samsung 850 EVO 250 GB
- SO: 10.10.3
Che cosa ho cercato di trovare il problema?
- Reimposta la mia PRAM
- Ha disinstallato tutte le estensioni del kernel non necessarie, ma ha mantenuto quanto segue:
at.obdev.nke.LittleSnitch (4240)
com.globaldelight.driver.BoomDevice (1.3)
com.viscosityvpn.Viscosity.tap (1.0)
com.viscosityvpn.Viscosity.tun (1.0)
- Esegui sia il test hardware normale che esteso. Nessun problema trovato.
- Utility disco usata per verificare la presenza di errori. Tutto andava bene.
- Ho anche un sacco di Kernel Panics che devono con IOGraphicsFamily . Potrebbero essere coincidenze o non correlate?

Che cosa posso fare per risolvere questi problemi?
Questi problemi sono piuttosto fastidiosi. Questo significa che la mia scheda grafica sta morendo (e io sono sfortunato), o si tratta di un problema noto e, si spera, una soluzione?
