Rendering-problems on High DPI mode #2878

Open Alxandr opened 10 years ago

Alxandr commented 10 years ago

When using chrome with High DPI mode (currently at chrome 37 dev), there are black borders around the editor (see image). Also, it's unbelievably slow, which makes it almost useless for editing. I end up starting the editor to get the web-server going, then just doing coding in another editor.

Thanks for the feedback! High DPI mode isn't something we've tested. Do you see performance issues with it off as well, or only with that mode on?

Yeah. Sure. I get that. Just figured you'd like to know, cause eventually you'd probably might want to support it. And for all any of us know, it might be a quick fix, or just some strange bug caused by a corner case nobody thought about.

But anyways, with regards to the performance issues, they showed up when I turned on High DPI mode (and upgraded chrome to 37 (if I recall correctly) alpha, to get back the High DPI mode that got shuffled around a bit). I'm not too surprised by seeing some performance loss with high dpi mode, I mean it obviously strains my PC more, but the amount I'm seeing with the CDE is a lot more than anticipated. And I don't think the problem lies with ACE (though, I will test this when I get back home to my laptop). Cause I think I've used ACE quite successfully (in C9 IDE for instance) without any problems at all.

No, thanks for the report. I just wanted to confirm that the slowdown was something you were only seeing with high dpi mode enabled. It could be something we're doing which is harmless in general, but hits an issues w/ the high dpi mode.
