Gwenview with lines when fractional HiDPI scaling is enabled
SUMMARY
My Gwenview is drawing lines on the image when fractional HiDPI scaling is
enabled. Not exclusive to the mentioned version, it's happening a long time
ago.
STEPS TO REPRODUCE
1. Change global scale by 1.4 (I think other value results the same problem,
but I use 1.4)
2. Open the image:
https://drive.google.com/open?id=1_5-aNgr2bw88vipVer2c8szhhhonuJ-B (doesn't
happen with all images, so open that one)
3. press CONTROL+ to add zoom so that the user can drag the image up-down and
left-right
4. drag the image up-down and left-right
OBSERVED RESULT
Horizontal and vertical lines on the image as attached file as attached file
EXPECTED RESULT
Horizontal and vertical lines on the image as attached file as attached file
