Ilustration for poor image quality in Writer
Very poor quality of inserted images in Writer - see attachment. Left side shows picture in WPS Writer, Right side shows same picture in LibreOffice Writer, and You easily can see image distortion in LO Writer.
Hi @menulio, thanks for reporting.
Have you activated the option:
Menu/Tools/Options/LibreOffice/View - Graphics output
to use hardware acceleration and anti-aliasing.
Under Graphics output two options of four are checked:
[checked] Use hardware acceleration
[checked] Use anti-aliasing
[not checked] Use OpenGL for all rendering
[not checked] Force OpenGL ....
Each image type for both raster and vector images has to be rendered by filter into native bitmap for display on the document canvas. And additional filter processing for export or printing.
Specific filters require additional "helper" files to render the images.
Please identify the image type and origin that you are having rendering issues with. Also, would be best to attach both the source image, and a test document.

Test document with a test picture

The .PNG raster image is only 800x656 pixels at 192ppi in the document. Or at 75dpi on ~A4 paper. That is not a very high resolution image to start with.
Its rendering as bitmap on the document canvas appears correct.
Is there a different original of the graph being used in the WPS document? In EPS or EMF/WMF perhaps?

Print screen of LO Writer and WPS Writer
A bug still exists in LO Writer even I use PNG images with bigger resolution / DPI.
Left side - WPS Writer, right side - LO Writer.
Isn't this the same as
