Bug ID: 501146
Summary: Hard to get exact window sizes for some resolutions.
Classification: Plasma
Product: kwin
Version: 6.2.4
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: evors...@protonmail.com
Target Milestone: ---
SUMMARY
OK, so I do a bit of screen recording and gaming and video editing on my KDE
Linux workstation.
When video editing, using standard resolutions are preferred, like 1920x1080.
It then makes sense to capture the screen at this resolution. Video cameras
support this resolution and so on.
The issue comes in when using my laptop's panel, which is 2560x1440. I could
just set the resolution there to 1920x1080, but then I am left with display
artifacts which I don't get when applying scaling.
When applying scaling, there is no scale that will give the a virtual
resolution of 1920x1080.
As you are no doubt aware, when scaling the monitor you only have percentages
to work with, and after applying a scaling factor, applications are given a
resolution that is the product of the native resolution and the scaling
percentage.
Unfortunately, 2560x1440 is exactly one third larger than 1920x1080, which
would require a scaling percentage of 133.333333333 % (Which you can't set) to
get an virtual scale of 1920x1080 on a 2560x1440 panel.
OBSERVED RESULT
No scaling options that result in standard output sizes.
EXPECTED RESULT
Scaling options to exist which scale the display to standard sizes.

ADDITIONAL INFORMATION
I know this is a stretch, but it would be really nice to be able to specify the
output resolution for the scaling, rather than the percentage. I know people
are used to the percentage thing now, but if scaling could be toggled between
percentage and effective screen resolutions with options that would be totally
awesome.
