Bug ID: 346006
Summary: Freeze and crash when editing multiline text
Product: krita
Version: 2.9
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: Vector Objects and Tools
Assignee: krita-bugs-***@kde.org
Reporter: ***@mail.com

Krita freezes when editing multiline text. I was trying to cancel highlighting
the texts by inserting a space. The interface shifts between grey-out and
normal, but not responsive either way. I force quit the application and Krita
crashed.

Reproducible: Always

Steps to Reproduce:
1. Insert a section of multiline text;
2. Make the texts red, now the texts are highlighted;
3. Switch to Shape Handling Tool, drags the handles around;
4. Use Text tool to edit the texts;
5. Try input a space and using the arrow keys to move input mark;
6. Krita freezes;

I'm not able to reproduce, is this still happening to you?

Hello Tyson, I've just checked following the steps above, with the latest
version of Krita: 2.9.5 (git 9fe0557) on Ubuntu 14.04.
I've tried several times, but I haven't been able to reproduce the issue.

There were crashes. Probably related to the implement of multiple document
interface and it's now fixed...probably? But there is still huge slowdown or
outright not responsive to my input all time when I use Multiline text tool.

1. Major slowdown. Every letter I input takes more than 100ms to show up. And
if I select some text and try to change its color or something, it will take a
few seconds, sometimes even much longer for the according Tool options (now in
the toolbar) to show up. I think it was the slowdown that I took it as
freezing. Fairly so if the slowdown locks up Krita for a minute with its UI
gray out.

2. When using Multiline tool and Shape handling tool with a tablet stylus, the
cursor flickers back and forth among mouse pointer / hand / text indicator.
After the first input, hovering the cursor through the canvas, I can see brush
size bar and its value changes like crazy but it's also grey out. Sometimes the
cursor becomes a brush and I can not even edit. Was the brush tool activated
when I was using text tool? FYI, there are a handful of other tools and UI
components in Krita that are fine with mouse but problematic with tablet
stylus.

3. CPU usage sky-rockets during each action when using Multiline text tool. I'm
using Thinkpad X230t, it sports an i7-3520M with 16GB dual DDR3-1866 memory
which I suppose fairly mainstream if not powerful. It's always dead silent
except on two occasions: Building Krita / Using Krita's multiline text tool. ;b

Is there anyway to track performance issue for the text tool?

Hi... Let's track all the multiline text tool bugs in 306181 -- it needs
rewriting in any case, and a redesign.
