'undo' clears all previous stroke input

Post  wujian on Mon 20 Mar 2017, 5:39 pm

Hi,

Here is another problem:
First I input quite a few strokes, but if I press shortcut 'z' to undo the last stroke, it either clears all the previous strokes, or the past strokes are not displayed correctly.
Press 'x' to redo does not help. When you undo, I believe, some data has already been lost. So this must have something to do with the undo cache data.

You might want to try my artwork file here (expire in 2 days):

PC specs:
Win 7
Ram 16G
GPU 4G (nvidia k4100m)
The specs should be quite satisfactory for almost any apps.

Thanks for your reports!
This week I don't have an nvidia GPU with me to check, but nvidia GPU's have been working quite well with Expresii in my experience for the crop/expand and undo/redo functions.
The only thing is that there may be issue when you have a very large paper - I see your attached artwork is max'ed at 24x24 units - which is huge.
On my Surface Pro 4, I do get error when cropping it (but it could be only for the Intel GPU that SP4 has, but again, currently I don't have an nvidia CPU to test with so I can't say for sure yet)

Will get back to you after I do more testing.

I now have a nvidia to test with again. I realized if paper size is max'ed at 24x24 units, things would go wrong. If I go only 20x20 units, things are good (crop/expand/undo/redo all working). In the Normal User mode, the max dimension is 16. Advanced User mode 24. Now I think I'll simply make it 20 to avoid ppl encountering those issues you mentioned. Smile

Hi Admin
Please note if you export to png at maximum size (x16), most probably you will encounter errors. I think the reasons are the same.
