Blurry graphic

SUMMARY
Since the update to 22.08 the graphic that shows the result of a scan in Filelight is very blurry. The text in the center that displays the total size is affected as well.

Comment 2 Nate Graham 2022-08-23 09:33:09 UTC
Are either of you folks using a scale factor that's not 100%, 200%, or 300%?
Comment 3 Harald Sitter 2022-08-23 09:48:11 UTC
.
Comment 4 Sandro 2022-08-23 18:30:47 UTC
I do, 125%. I tested it with scale factor set to 100% now and everything looks fine. So seems to be related to scaling.
Comment 5 Ilya Bizyaev 2022-08-23 20:57:01 UTC
Also 125% here.

Don't know if it's relevant, but I tried changing Filelight's scale to an integer with an env var to get a crisp screenshot (QT_SCALE_FACTOR=1 filelight, QT_SCALE_FACTOR=2 filelight) — but the diagram was still blurred.

Comment 8 Henry Zhang 2022-09-09 10:27:58 UTC
22.08.1 doesn't fix the issue, it still looks blurry on my machine.

x11, 150% scaling

e873c3bfa2e6f971e1699a5377a0e46c7e363442 is the first bad commit.

Alas, after some poking I'm not sure we'll get this crisper until a complete port away from qpainter.
