When I installed APG 3.0.1 Pano editore opened in maximized window (2560x1600) with destroyed (sheared pano rendering).
While trying to get some helpful information about what/why I discovered that making the editor window smaller helps.
To describe the behaviour I performed following steps:
1. maximize the editor window up to the size which is still OK - screenshot *_OK.png
2. slightly increase editor window size - this flips image upside down by horizontal axis (not 180 rotate, I believe) - screenshot *_flipped.png
3. increasing window further - image shears - screenshot *_shears.png
4. reducing editor window size goes through the same sequence of events - it is repeatable just by stretching or contracting.
I admit that this could be driver issue - in that case it might be better not to maximize the window initially.
I cannot verify it as I do not have any other GPU or PC able to drive up to 2560x1600
APG 3.0.0 behaves identically.
CPU - IVB - i7 3770S using internal GPU HD 4000 - 16GB RAM
I hope it helps, Tomas

This might or might not be related:
I noticed when stitching high Mpx images - that when zoom in enough in the pano editor the preview GPU rendered image goes black. In my case image preview goes black at around 40% zoom with 3x24Mpx images.
Zoom level when this (black preview) happens depends very much on the file size/mpx of the stitched images. The bigger the images lower the zoom level possible. Almost like a buffer limitation on maximum number of rendered pixels - like the preview render buffer takes full image instead of the visible window rectangle - so zooming in fills preview render buffer with too many pixels outside window rectangle. Just my interpretation of the behaviour.
Using the new render preview button helps - enables high zoom levels in preview - this is fine for setting verticals - but does not help/work in (un)ghost mask point placement. This is somehow inconsistent behaviour of the render preview button in Mask Edition mode - visible in this case of CPU ender issues.
I hope this makes sense and helps in identifying the problem/solution space, Tomas

Hello Tomas,
From what you explained, it really looks like a driver issue. We may have to check if there are any updates for your driver on the manufacturer website. You can also try to disable GPU usage in application settings.
Let us knwo if it fixes the issue.
Regards,
Thomas

Driver is part of Linux kernel, so not that easy to apply the way you are suggesting.
Were you able to try it on your side? I hope that IVB with HD4000 is relatively common these days. It would help trouble shooting, if you try.
If you tried to reproduce it and everything is fine on your side - would you be able to post some info about what linux did you try it with, so I can see if that combination would help me too? Was my description detailed enough for you to understand how to replicate it?
When disabling GPU I still cannot zoom in (un)ghost mask point placement as originally reported.
Best regards, Tomas

This kind of display has been often corrected by updating the driver (more easy with ati or nvidia). So, we can't fix something which depends on us... By the way you can try the "compatibility" option in GPU general settings. It's just another way for doing same things and sometimes it help to work around GPU driver bug.
In all tools, new preview is displayed in background and current pictures (with low resolution in CPU mode) are displayed over this preview. In line mode, there is no current picture (so you always see the preview with good resolution). In mask mode, current picture is the one under the mouse. So, you can move the mouse outside the display area to see the preview at screen resolution and go back inside to add markers on low resolution pictures.

Thank you for your responses
.... and my apology for not stopping by to check earlier.
