ModEdit; related ticket: #18957: Frequent freezes in display output since 6.0
Since I updated from 5.2.22 to 6.0.2 (and now 6.0.4) I often have problems with my Windows 10 guest (I don't use any other guests, but a friend who uses 6.0 with Linux guests has no problems, so I assume this is Windows only). The problems manifest as freezes/pauses/hangs in the UI. The whole display output freezes and a bit later suddenly jumps to the desired output. This is especially visible in continuus animations, but annoying everywhere, especially while typing text.
Here is what I could find:
- The freezes happen every few seconds and last for about half a second.
- It affects all programs and also the windows desktop at the same time, so it looks like it is the VirtualBox display output itself that's causing the problem.
- Both VBoxVGA and VBoxSVGA show the same problem.
- The problems only start on boot or resume (from a saved state) of a guest. Once a guest is running fine, the problem does not suddenly appear as long as the guest stays running. But shutting down or saving the state of the guest has a high chance of showing the problem on the next boot/resume.
- I'm not 100% sure on this one, but it seems like a guest reboot doesn't fix the problem. Instead a shutdown and "cold" boot is required.
What is the best way to get this fixed soon? Should I create a ticket?
Guest additions are updated. Logs are attached in case someone can see a problem there.
I know that I've assiged all my CPU cores to the guest but that is intented. I hardly use my host at all and the guest should have all the performance that it can get. Reducing the cores the guest has access to doesn't fix the problem.
