Navigation in Help is slow when full-screen

Post by zb! »

Hi there,

It's basically all in the title: When using the cursor keys to navigate up/down the help topics (F1), navigation is slow when you're in full screen (ALT-F9).

Is there anything I can do about it?

Cheers,
zb!

First of all, as with any bugreport (and as specified in the Far FAQ you translated a while ago), please specify the exact version of FAR (e.g. as displayed under the panels upon startup), your Windows version, and whether the issue reproduces if you start FAR with no plugins (use the -p command line switch). Ideally, please check on other computers too.

The test below confirms it.
In non-fullscreen mode: 55 ms, in fullscreen mode: 600 ms.

Code: Select all

Macro {
  area="Help"; key="F1"; flags="EnableOutput";
  action=function()
    tt=Far.UpTime;  Keys("20*Down"); far.Message(Far.UpTime-tt)
  end;
}
P.S. With far2m (Linux) the average results are 40 ms in both test cases.

Sorry about that.

I'm experiencing this at the moment with Far Manager, version 3.0.6000.0 x86 on Microsoft Windows [Version 10.0.19045.2846].
The issue remains when running FAR without plugins. I'll try to reproduce on another machine, too.

Update: I've tested another machine with the same FAR version, but Microsoft Windows [Version 6.1.7601].
The slow scrolling is clearly noticeable there as well, although less pronounced...
It feels like it has something to do with the monitor size (the Windows 10 machine has a much larger one).

Unfortunately it has. Help rendering complexity is quadratic-ish to the screen size.
It should be more bearable starting from 6142.
Thanks for reporting.
