Re: Fw: Staggered Cursor Movement in RDi V9 -- WDSCI-L

V9 does seem less efficient on scrolling up and down or left to right.
Scrolling in DDS source is atrocious. I guess its not bad enough that I'll
downgrade though.

Darren,

Watched on my system, one core peaks at 20% for the duration of scrolling.

I mentioned it to one of the "pc dudes" and he swapped out my video card
for a newer one (wow, DVI ports!). Same situation, made no difference at
all (messed up my desktop though).

On this PC, 8.5.1 still does not do it. Nice and smooth.

I'll quit harping on it now and live with it.

80%. If I paste that source into a text file in the editor, there is
virtually no CPU hit. I tried turning off every feature I could find

had to do with parsing or outlining, and nothing seems to make a

imagine a problem like yours occurring if my system wasn't able to get
enough CPU resources. And, I don't recall RDp 8.5.1 doing this quite so
badly, although over the different releases and computer systems I've

had,

I have had similar spikes in CPU usage when scrolling.

More pain to reconfigure all the connections and filters.

Anyway, tried that new workspace deal. The blinky effect still occurs
(it's probably my system), but the cursors are somewhat more

synchronized.

The OP stated that is it much worse using the spacebar (like moving a

line

right by inserting spaces) and he's right, the format line cursor is

frozen

in place until you release the spacebar, even in an empty workspace.

Perhaps I'll lay some pain on my PC guy and dig up a newer video card and
see what happens.

Sure I'll try that, but what's the point of have a workspace full of
settings if I have to make a new empty one all the time and lose all

the

settings? I never understood that as a solution to anything.

As an experiment, you might try creating a new workspace (without

I

Edmund

Both issues are present for any source member: C, UIM, TXT, DDS, etc.

When

in RPGLE with Auto-outline, they're just much worse.

Neither issue is present for any source member type in 8.5.1

Neither issue is present in v9 on my co-worker's machine, which is

similar

in configuration.

Cursor disappearing:
Happens at all times with the auto-outline ON. When OFF, the

duplicate

cursor at the top lags 1 space (sometimes several) behind the real

cursor,

but it does move. Usually it just sits in column 1 till you let go

the

arrow key. To reproduce: Open a member (any source type will do).

Right

arrow accross any line to the end. Format line cursor does not move

lags

behind regular cursor some distance. Often progresses in chunks of 5

or

10

characters.

Blinky text:
The blinking shimmering text may be my video card but I have failed

explain to myself why 9 does it an 8.5.1 does not, even running at

the

same

time side-by-side. Perhaps Eclipse's drawing routines changed in

such

a

manner as to tax my video card where it did not before in 3.4. To
reproduce: Open a member. Even a 20-line C module will do (does not

seem

to pertain to source type). Just down arrow from top to bottom.

Blinky

redrawing artifacts ensue, format line cursor is frozen, or delayed,

lags behind regular cursor.

I am not a PMR-worthy user.

Stu, I would need to reproduce this in order to fix it.
Can I first confirm that this lag only happens in ILE RPG with the

dynamic

outline?
Does this only happen with large members, or members with lots of

being referenced?
To be honest I can't figure out what could cause this, so if you

can

consistently reproduce it, please open a PMR, so we can get your
environment and figure this out.

Folks,

I just noticed this behaviour as well. I have a RocketSled PC with

96

TB

of physical ram (ha) and WinXP. Really, it is plenty juicy.

Decent

video

card as well.

It is very annoying, as when I am using the arrows I watch the

ruler

at

the

top to see where I am on the line. Well, used to. It is bad with

the

arrow keys, is it far worse with the spacebar.

The symptoms described in the OP did not happen in 8.5.1 with any
regularity (until you got to the 1024MB storage threshold, but then
everything went bad). In fact, I can run them side-by-side and V9

does

it

and 8.5.1 does not. I'll add that the duplicate cursor in the

ruler

area

at t he top also disappears.

I have also noticed that just using the arrow key to go up one page

(from

bottom to top of one page without scrolling it) blinks the whole

page

as

it

redraws the text on every keystroke. It's sort of psychedelic as

the

lines

ripple and shimmer with white space streaking though them. Again,

8.5.1

did not ever do this and still does not today.

Perhaps the live parsing in V9 took a hit and now affects the

display.

Parsing on every keystroke (per Edmund) might be a bit much, and

that's

probably where the issue lies. Anyway, it sounds like an issue to

investigated. A poor solution would be to have to disable the

"more

timely" outline mode as that is easily 30% of the benefit of RDi.

IMO.

I used this to toggle the outline settings and it seems to have

Thanks for pointing me in the direction of the live outline

toggle.
