If you find mtpaint slow to open read on

Recently I found mtpaint very slow to open. About 30 seconds and I have a decent PC and running Debian Testing branch

Running it from a terminal gave no errors (it opens so I accept that)

so I downloaded from
https://github.com/wjaguar/mtPaint/a...ads/master.zip

Development files for compiling are mentioned here
https://github.com/wjaguar/mtPaint/tree/master

after installing them....I chose heaps....YMMV

Code:unzip *zip
cd mtPaint-master
./configure gtk3

make -j5
su - # or however you become root
make install
mtpaint --version
# response is mtPaint 3.50.09and it opens within 2 seconds like I love.

to test file format versions are all available (or the ones you chose) you need to open an image file first, you get misleading results if you try to just open mtpaint without opening a file......and then click on file save as and then click the file format pulldown

Hope that helps someone
