Moving to 4.9 due to work on hidpi support on KDE
Comment 3 Sravan Kumar Lakkimsetti CLA 2018-08-29 04:40:14 EDT 
After a lot of investigation we could not find the root cause yet. Moving to 4.10
Comment 4 Peter Severin CLA 2018-09-20 03:20:22 EDT 
This bug was partially fixed in Bug 535064. Now the smaller problem that remains is the fact that the chevron is blurry on x2 display. See the attached screenshot.

See Bug 535068 for the blurriness
Comment 7 Sravan Kumar Lakkimsetti CLA 2018-11-16 04:21:36 EST 
We are currently working on Hidpi support on Mac. Will be looking in to this in 4.11
Comment 8 Sravan Kumar Lakkimsetti CLA 2019-02-13 04:31:16 EST 
Currently working on getting 489451 to completion. Will have a look in 4.12
Comment 9 Sravan Kumar Lakkimsetti CLA 2019-05-15 04:29:16 EDT 
The problem here is in Linux we create blank images at 100% regardless of scalefactor. This needs to to rectified.

The fix for this probably fix bug 534422 as well. 

I found the root cause. but fixing will take sometime. It will be too risky for 4.12. Moving to 4.13

Sravan, is this still an issue?
Comment 11 Sravan Kumar Lakkimsetti CLA 2019-08-14 00:37:10 EDT 
yes it is still issue. this is also causes blurry images for composite images.

(In reply to Sravan Kumar Lakkimsetti from comment #11)

Moving to 4.14 then.
Comment 13 Sravan Kumar Lakkimsetti CLA 2019-11-27 03:51:25 EST 
Moving to 4.15
Comment 14 Sravan Kumar Lakkimsetti CLA 2020-02-19 03:53:06 EST 
Removing target as I could not find time to fix this. Please retarget if anyone is willing to work on this. 

This is related to bug 534422 and both have same root cause
