Serious copy/paste bug in X6

[foxyrick]

I've been using X6 for a week now, and I have to give up on it completely due to this bug. It makes the program unusable for much of what I do.

When the image is scaled larger than the size of the viewing window ("workspace"?) the copy and paste does not work correctly. My X6 is the very latest version 16.1.0.48 installed from the latest download. The issue occurs on both 32 and 64 bit versions.

I am trying to simply select and copy a part of the image, and then try to paste that part back in to the image in another location, using CTRL-C and CTRL-E. Nothing fancy, only one layer, basic .jpg images.

The pasted selection does not display or move properly. When I try to drag it into place, parts of the selection disappear completely and other parts leave 'trails' across the image. This stays on the display until I re-zoom. Given that I do this a lot in the images that I work on, it is practically impossible for me to work with X6.

Fitting the entire image into the workspace window prevents the above issue, but given that I am trying to position with single-pixel accuracy on images often several thousand pixels square, that is not viable.

Is there likely to be a fix for this?

For what it is worth, I have updated my graphics card drivers and my Windows (7 x64 Ult) is fully up to date.

There is a second bug that I see frequently which is not a show stopper, but is still irritating.

If I use the clone tool to move small parts of an image to another area, when I then click on another tool (typically the selection tool) the part that I just cloned over reappears as I had done nothing to it. If I re-zoom, my changes are then shown so the clone tool is working, just a display bug.

I really hope these issues (especially the first) can be addressed. A t the moment I simply cannot use X6 to work.

Your version includes SP1 which fixed some things and broke others. Corel has issued a hot fix which should correct some or all of the issues. Here's a link to the topic.

Thanks, I've already installed that hotfix (I should have mentioned that). I hoped it would address this issue but it made no difference.

There is also another possible bug that I have noticed:

If I roll the mouse scroll wheel very quickly (to zoom) sometimes PSP loses focus and whatever application is behind it comes to the foreground. This has variously been my email client, explorer and ACDSee.

I do not know of that is a bug in PSP but I have never observed the behaviour before or with anything else and I often scroll that quickly in other applications.

I have not experienced either of those "bugs" in my laptop using an image that is 5616 x 3744 pixels. Control C and Control E paste as new selection work correctly with a small 10 x 10 pixel section . With Control E the copied section behaves like a bit of tape stuck to the cursor and moves with that . Have image scaled 800 % so definitely occuppies full screen. When I click it becomes a floating selection which can still be moved around without any trails that you have described.

Likewise cloning a small section at the same magnification did not revert when I changed tools.
So here is one person that cannot reproduce that "bug"

Why "bug"? It sounds like you are questioning what I say.

OK, I'm glad you don't have these problems.

I, on the other hand, can reproduce them both easily and repeatable; every time I use the program.

I'm not exactly inexperienced with PSP, having used it personally long before Corel bought it, and I use PSP X4 extensively at work and previously on this PC. X4 does not have the aforementioned bugs and I work exactly the same way in them both.

This bug has been discussed in a number of postings. I call it failure to redraw properly. It seems to happen for me when working on an image that I've zoomed in on. Most recently I was trying to edit text and I was getting strange coloured areas - I realized it was a recurrence of the redraw, zoomed out and the selection had worked as expected. I think this problem was introduced with SP1 and the hotfix seemed to help but obviously it is recurring. It may be occurring only with vectors, not sure A pain but whenever I realize what is going on I zoom out and back in again. Where is SP2 to fix SP1?

Is there a difference whether one uses Tabbed Documents or Untabbed Windows?

Also, SP1 Release Notes say: "Enhanced support for high-resolution displays". Could this be an issue?

I find that this is a problem that is not reproducible - it seems to me it comes and goes and I have not detected a pattern yet. I tried some moves with tabbed and cascade views but it was inconclusive - no glitches in either.

Regarding the high-resolution display, the last time the display was breaking up was with a relatively small graphic with a resolution of 200 ppi - doesn't sound as if that fits the bill.

I have mentioned the word bug because that is what you mentioned in your heading. I put it in quotes because I believe a bug is something that is reproducible in a large number (majority?) of systems which this does not seem to be. So there must be a certain set of circumstances that cause this to occur in some systems and not others.
As has been mentioned it seems to be related to the refresh rate of the system. So the question becomes what causes the refresh rate to be slowed in some cases and at some times but not on other systems at all.

The refresh rate is a function of the monitor, but also of the graphics card. Presuming that the monitor is not misbehaving, what could cause the graphics card to slow down at some times and not at others, and on some systems and not others.
I apologise foxyrick if you thought I was doubting you, but I am wary of calling all malfunctions bugs, glitch perhaps but not a defined bug.
You can now accuse me of playing with semantics and I accept that.

Could it be because of overtaxing of the computer's systems. I did my tests with only a windows folder and X6 open. I have noticed slowness before in computers when a virus checker was doing a full scan. May be other programs running at the same time could cause slow downs in the refresh rates?

At least you didn't pull a Microsoft on me and tell me "it's a feature", I'm used to glitches etc. having been a Microsoft beta tester for many years and a systems analyst/programmer.

I doubt it is related to other PC activity. I reformatted and reinstalled my system only a fortnight ago and only have a few applications on it at the moment. It's a quad core with 16GB of RAM, and I can reproduce the issue at will.

Having read the above posts, I tried turning off 'tabbed windows' and my main problem does not seem to occur in that mode, so far. Shame because I really like tabbed document interfaces (I even paid extra for an add-on for MS Office for it).

I also noticed this morning that the problem seems to occur (in tabbed mode, that is) if I move the selection off the top or left edges of the actual image. It then continues to happen; possibly a simple glitch in the code that tracks the position. If I am careful not to do that, the issue seems not to happen although redrawing the selection as I move it seems slower than in non-tabbed mode. Unfortunately I tend to work around the edges a lot.

I'll plod on in non-tabbed mode for a while and see if things continue OK. Hopefully a fix will be forthcoming...

Edit to add:

Hmm... working in non-tabbed mode loses the very thing I had been finding so useful in X6 compared to X4. That is, the ability to move the selection cursor outside of the actual image, when it is zoomed larger than the workspace. That makes it much easier to select a portion of the image that starts at the very edge. Oh well... I'll have to switch between modes as I work.

[hartpaul]

There you go , a bit of detective work solves the when. I only use documents in untabbed mode as I may often neeed to match a colour on one image to the same colour on another image and it is easier to have the two images visible and side by side to do this.
On a positive I managed to get your refresh problem, but only using a very large image zoomed in and had to move the selected bit around fairly quickly to get it to leave a trial.

I don't see any difference between how it works in X6 with X4 or even in PSP8. As long as the image is maximized (either tabbed or untabbed and maximized), I can start to drag the marquee from outside the image boundary when zoomed in, at least with the shape selections. With Freehand selections, I don't see the selection outline outside the image boundary in any version, tabbed or not.
