- There are no consistent steps unfortunately however it’s worth noting that I’m running the X.org server from CentOS 6.7 which might also mean that newer X.org server versions are immune to this issue.
The reasons I’m running this X.org server release is because X.org from CentOS 6.8/6.9 is very buggy and starts consuming 100% of one CPU core shortly after logging into your X session.
- This is not necessary at all, however once you’re running a Zcash miner (EWBF in my case) everything becomes so slow, you just cannot help but notice this bug better and sooner.
I would not recommend trying to reproduce this issue when running the miner since it requires too much patience.
Running EWBF is extremely easy. Generate a Bitcoin address or use an existing one and start mining this way:
miner --server equihash.usa.nicehash.com --port 3357 --user YOUR_BTC_ADDRESS --pass x
Nope, there isn’t one, sorry.
Nope, however EWBF surely runs using CUDA.
This is the trickiest part. You’re just moving your mouse and sometimes it stays where it shouldn’t be. There is no surefire way to reproduce this issue - it’s extremely random. Also I’ve just realized that it takes quite some (at least an hour) before you start seeing the problem. I’ve just started my X.org session and no matter how hard I try I cannot reproduce it.
If you’re switching from an application to an application, or scrolling or moving mouse it may happen as often as once every 5 minutes however if you don’t move your mouse or you’re working in a single application it may never occur.
I meant that running any compositing manager (based on OpenGL/EGL) is not required, but you’re right that it’s reproducible with the bare X.org server started as the only running application plus at least one other application is required, e.g. Mozilla Firefox.
If you don’t mind let’s make this way. I will try to find a way to reproduce it or certain steps that make it easier to reproduce and I’ll update this topic.
Meanwhile you could close this bug report as CANNOT REPRODUCE or anything like that because surely I don’t want to waste the precious time of your engineers.
