What do you see for those images? A skull? A black image? Maybe it just takes a while for darktable to compute the big preview?
What I noticed is that on Windows keeping
z pressed is not working that great, the key repeat mechanism is kicking in and makes it flicker.
I already found the configuration (plugins/lighttable/low_quality_thumbnails=TRUE) but when I change it to FALSE, the file will change back immediately to TRUE after opening darktable…
Was darktable running while you were editing the file? The only code in all of darktable that is setting that value is when starting without any existing config so darktable tries to auto-detect some sane defaults.
I can’t find the print module, I only have lighttable, darktable, diashow, map and tethering…
Printing is not supported on Windows. darktable relies on Cups for that, which is not available for Windows.
Is there any way to scroll by mouse through the lighttable? (PageUp/Down I know…)
The mouse wheel should work fine.
With the previous version I had sometimes pictures with artefacts on int the lighttable preview and also on exported pictures (part of the image is repeated several times in the top of the picture…), but I can’t reproduce this now… (probably solved?!)
Hard to tell, just keep an eye open and report when it happens again.
And is there any way to slow down the export? Since I have a small Convertible, which gets pretty hot on exporting several pictures… I have tried with and without open CL, but can’t notice any difference, neither in speed nor in temperature…
That is a rather unusual request, most people want the opposite.
darktable has no means to slow down the export. However, there is the undocumented command line switch
-t that allows to limit the number of parallel threads used for computations. Try starting darktable with
-t 1 and see if that is slow enough for you.
