Cura 2.7.0 Font issue on OSX

[nicholaswagner]

Just installed Cura 2.7 on OSX. Getting the strange font issue in the attached screenshot.
I've included my system info incase that helps someone.

Happy to provide more details if required.

[nallath]

Oh wow. That's the first time i've seen it do something like that. @Appesteijn Could you check if it does the same on your machine?

[supersoulman]

same on my system. Cura 2.7.0. OS 10.12.6

[Ghostkeeper]

Perhaps the text is no longer pixel-aligned due to the screen DPI.

[prankard]

I'm having the same issue on Mac 10.12.6 (caveat, running hackintosh, though not had this been an issue in any software):

[Appesteijn]

I also run 10.12.6 but haven't seen this kind of font issue. If you change your resolution and restart Cura, does it still look like this? We do have a new version of Cura coming out in a few weeks, not sure if this is fixed in there.

[prankard]

Thanks for looking into the issue, the fonts on load appear to be fine, but updating values (like when slicing) the values change and it reloads the fonts and becomes an issue.
Tested scaled at 720p and default for display (1080p).
I am running 3 physical monitors and cura is on the second screen. I'll try unplugging the other two and see if the problem persists.

[prankard]

Tested with one monitor.
It happens less frequently when updating values than on 3 monitors, but when loading/reloading a model it can appear more on the blue status bar, then eventually can happen on print time remaining.

By the way I'm using GTX 960 with Nvidea Web Drivers 378.05.05.25f01.

[prankard]

Previously I upgraded from 2.4.0 which font worked correctly.
Deleted the 2.7.
I tested 2.6.2 and that version font works correctly on my machine, deleted that version and downloaded installed 2.7 and it has the same issue.
Deleted that app, and installed 2.7.0-BETA and it has the same issue also.

[Ghostkeeper]

The problem that Nicolaswagner has is recognisable. Seen it before. It's text being misaligned. But the problem that Prankard has seems quite different to me. The rendering seems jumbled up.

the fonts on load appear to be fine, but updating values (like when slicing) the values change and it reloads the fonts and becomes an issue.

Since 2.6 didn't have the issue and 2.7 did, I'm guessing that Prankard has found a Qt bug. I can't find any previously reported bug about it though, and I'm not able to verify that it is a Qt bug since it doesn't happen on my computers.

[ChrisTerBeke]

Has 3.0 or 3.1 been any improvement for you?

[Jerooney]

Another MacOS font issue popped up, it looks familiar but affects almost all text in the sidebar!
Any updates on this?

Cura version: 3.2
OS: Mac OS 10.13.2 (High Sierra)
Graphics: Nvidia Geforce GT650M

[prankard]

Still have the issue on 3.2 on my Hackintosh Mac NVidea GTX960 running 10.12.6
I now have Hackintosh Laptop (with intel chipset graphics) which doesn't have the font issue.

[Appesteijn]

We plan changing the font in the next sprint. We hope this will also solve this weirdness.

[fieldOfView]

We hope this will also solve this weirdness.

That hypothesis can be tested fairly easily.
@prankard, can you open Cura, then go to Help -> Show Configuration Folder. In the folder that opens, there should be a folder named "themes". In that themes folder, create a new folder named "default_font".
Download theme.json from this page https://gist.github.com/fieldOfView/3e94440bcc66acfd014dd2f71f6a4885, and place it in the "default_font" folder.

Next, restart Cura and go into the preferences and select the newly added theme "Default font". You will have to restart Cura again after that. Once you do, Cura should use the system default font instead of the font supplied with Cura. If that fixes the issue, then @Appesteijn's idea of changing the font in Cura to fix this issue has merrit.

[prankard]

@fieldOfView I've just tried creating, selecting and restarting with the default_font theme enabled but still have the same issue:

[fieldOfView]

Thanks for testing. That likely means that switching the default font in the coming sprint will not fix this issue.

[Appesteijn]

Can we validate the hypothesis if updating to Qt 5.10 & PyQt 5.10 will solve this?

[Jerooney]

@Appesteijn , could you assign someone to validate the hypothesis you mentioned? I have not enough knowledge to do this.

[ianpaschal]

@Appesteijn Not sure if it belongs in this sprint, but something I could look into today while fiddling with fonts?

[Appesteijn]

Devs see CURA-4941.
I just made https://github.com/Ultimaker/Cura/pull/3270 hopefully this will fix it but I can't test it on my machine (as everything looks good there).

[prankard]

@Appesteijn Happy to test here but with a compiled build if you are willing to provide.

[Appesteijn]

Could you try Cura 3.2.1: https://stack.mybacklog.info/s/MgLnKXLL0P9ro4M ?

[prankard]

Font renders well in build 3.2.1. Congrats :)

Tested loading model, moving model to force slicing of model which previously messed up the fonts before. Opening closing grouped settings tabs and hovering over descriptions. All good!

[ianpaschal]

Thanks for testing @prankard! Just for our reference, is this working on a 72 dpi screen or a ~Retina~ high dpi one?

[prankard]

Working on a hackintosh with GTX 960, with three Benq GL2450 24inch Screens each running at 1080p.

[Appesteijn]

Could you try: https://stack.mybacklog.info/s/LDltcUP2BXur7AZ ?

[prankard]

@Appesteijn Tried that build, but it's not so good with the fonts.

[Appesteijn]

Ok I reverted the change. Thank you for testing.

[aivanis]

Same thing with my MacBook Pro Retina Mid-2012 (GT 650M)

[ianpaschal]

I believe this will be fixed in 3.3 with recent changes. If it's not, comment and we'll re-open.
