I have never had an issue with performance until yesterday. When I booted up the VM, I immediately noticed that everything was running super slowly... even just using Alt+Tab to switch windows was super laggy.
Running top, I saw that compiz was consistently using 100%+ CPU. I spent ALL of yesterday trying various things: rebooting, tweaking with the compiz-settings manager, even creating a brand-new VM-- only to observe the same lagginess (with compiz spiking)!
I checked the syslog and did find the following:
I'm really at a loss here... I'm wondering if some updates applied on the Windows side could somehow be affecting the performance of my VM?`compiz[2996]: segfault at 7f041577b800 ip 00007f0420bc6168 sp 00007ffe78334fd8 error 4 in libc-2.23.so[7f0420a78000+1c0000]`
I am running Version 5.2.18 r124319 of VirtualBox. Let me know if I can provide any details that might help solve the problem.
I'm really at a loss here, and would love to get the bottom of this.
