Please help: slow cursor movement between lines while in code view!


#1

Yes this may seem so bizarre but I simply can’t code because the cursor in code view moves so slowly between lines. When I press cursor up/down or use the mouse to click on another line there is a painful pause before the cursor appears at that new line… it’s very strange. Anyone faced or has any solution to this??


#2

Which version of AppStudio are you using?

How many lines of code do you have?


#3

v6.2.7.2. Just editing any of the short sample projects does this.


#4

That is bizarre. What kind of computer are you using? Have you tried restarting it?


#5

OK, I figured it out… but still no solution.

The issue only happens when I have a second display connected to my laptop. So, if I hook-up a big monitor and use it as the primary display the code editor slows-down. Using the code editor on my laptop’s monitor (without a second display connected) everything is good-to-go.

Now, my laptop (it’s a new Macbook running Windows 10 x64) is always connected to a second monitor when I’m in the office so this is a really bad situation to have.

Anyone have any ideas how to fix this…? much appreciated.

A couple of the guys here use this exact setup (MacBook with an external monitor) and it works great - but one difference: they are using Mac OS.

Is that an option for you? I suspect the actual issue is in Windows or the middleware being used to run Windows.


#7

Unfortunately I’m stuck with Windows… is there anything I can “tweak” to “fix” this… really makes AppStudio just unusable.


#8

How are you running Windows? Are you using BootCamp, Parallels or something else?


#9

Just BootCamp… Windows Pro installed on the HD and I boot into it straight.


#10

This doesn’t sound like something we can fix. We know that multiple screens on Windows works fine, and the multiple screens on Mac OS works fine. I suspect some interaction between BootCamp and Windows.

We just call the standard libraries - we are not doing any processing related to multiple screen.

Here’s a report of a similar issue with Parallels:

Here’s another one not involving AppStudio:

Some Macs have been known to spike the kernal_task when a second monitor is added. It requires SIP to be disabled then re-enabled. FYI: I don’t suggest this unless you really really have to do it. It also requires disabling kext files and clearing the kext cache.
