XnView Software

I fix it by removing libfreetype.so.6 from lib.
There is an incompatibility between the libfreetype provided and some system libraries (libcairo or something else).

open with associated problem doesn't work as well, similiar error:
engrampa: symbol lookup error: /lib/x86_64-linux-gnu/libcairo.so.2: undefined symbol: FT_Get_Var_Design_Coordinates

19.10

caja: symbol lookup error: /lib/x86_64-linux-gnu/libcairo.so.2: undefined symbol: FT_Get_Var_Design_Coordinates

catalog optimizing also uses 2gb+ memory and never release after finished

I'm using Ubuntu with Mate desktop. Until 0.94 I can open the photo folder with Caja file manager with the "explorer" command. However it is no longer working in 0.95.
Not yet tested with other file managers.

after some more test I think memory leak accurs mostly during photo editing, instead of thumbnail generating.

Just normal JPEGs taken by a DSLR, size 5~10MB.
It seems that it relates to thumbnail generating. I can see the memory usage of Xnview expands significantly after finish generating thumbnails of a new folder containing a lot of photos. After editing, new thumbnails generated and more memory used.

500-1500 in a folder

Yes, always. Sometimes it took just several minutes to eat up all memory, sometimes up to a hour.

It seems that there is a memory leak problem in recent versions of XnviewMP linux. When I view or edit photos in a folder containing hundreds of photos, all system memory (4gb in my computer) was eaten up in several minutes.

Will newer Qt library be used in 0.94?

It seems that something goes wrong with the rotate tool. When using it to edit an image, I sometimes get unacceptable results with jagged and dislocated lines like the example below. Using crop tool to rotate can get smooth lines as expected. original image: 1.JPG after rotated to 1 degree: 2.JPG

Is there any difficulty for using the newest Qt library in the next version?

Will it be fixed on upcoming 0.94?
