Re: [NTG-context] Bug: context/mtxrun makes Firefox eat up cpu

After dozens of compilations of various minimal examples using the newly installed context, the problem reappeared. Removing tex/texmf-cache does not help. Does anyone know what files context modifies apart from tex/texmf-cache? Sylvain On Wed, 4 Nov 2020 at 16:01, Sylvain Hubert wrote: >

The problem disappeared after a fresh installation of context with everything else untouched. On Thu, 29 Oct 2020 at 11:29, Sylvain Hubert wrote: > Hi, > > sorry if this is not the best place to file a bug but I found no working > bug tracker for context. > > Environment: > Manjaro 20.1.2,

Re: [NTG-context] Bug: context/mtxrun makes Firefox eat up cpu

Hi Sylvain, This bug tracker report describes lagging / freezing (which are symptoms of excessive CPU usage, of course) for versions of Firefox from 70 to 74 inclusive on Manjaro. They also report Chromium seeing the same problem. These

I've just tried chromium which behaves a bit better but still experiences a sudden raise of cpu usage from <10% to >70% during ~1s. I've also noticed that, even without any browser running, each time after I compile a file with `context`, my terminal get stuck for ~1s. So I'm pretty sure this is a

And using safe mode here is just to make sure that the problem is not caused by extensions. The annoyance started long before I bothered opening firefox with an extra argument. On Thu, 29 Oct 2020 at 12:02, Taco Hoekwater wrote: > > > > On 29 Oct 2020, at 11:29, Sylvain Hubert wrote: > > > >

Hi Taco, thanks for the suggestions, but as mentioned earlier, `mtxrun --script font --list --all` triggers the same problem as `context` does. I guess the problem might have something to do with fonts, but since `context` aka `luametatex` is not open source yet, I can't analyse further. Best,
