Re: [racket-users] Strange gray lines in DrRacket editor
One possibility is that Racket was working with GTK3 before, but GTK3 broke that (or broke your GTK3 theme) in a newer version. I've heard developer complaints about this, and about engineering culture changes and politics. Firefox might be a good example to look at. Some URLs that don't involve cursing or intrigue: https://wiki.archlinux.org/index.php/firefox#Firefox_looks_bad_with_GTK.2B_.3E.3D3.20 https://bugzilla.mozilla.org/show_bug.cgi?id=1268234 I no longer have a good long-term recommendation for open source desktop GUI toolkits; maybe next year. For now, I go to some trouble to use GTK2 apps whenever possible. The good news: for most of us developers using Racket on GNU/Linux, one nice side-effect of the Racket cross-platform desktop GUI stuff is that we don't have to decide whether to code for GTK2/GTK3/Qt/etc. -- we can shift all that pain onto Matthew, et al. :) -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

[racket-users] Strange gray lines in DrRacket editor
Hi again, Jaroslaw and everyone concerned. I have investigated a bit further on this issue. This is a quick report of my findings thus far. If I can provide more useful information, I'll do it in a new post. To summarize what I have found. 1. Artifacts are still there, though mitigated, even after applying the last proposed workarounds. 2. At least on Unix systems, the issue seems to be completely fixed by falling back to GTK2. More details. * Basic Machine description Platform: Dell XPS 13 9360. Graphics: Iris Plus Graphics 640 driven by the i915 module (default chipset settings) OS: Ubuntu 16.04.3 (Linux kernel: 4.10.0-33-generic) * Description of the issue Ghosting lines and/or little squares screen artifacts appears on the drracket canvas while scrolling. Much more prominent when text is scaled and/or when graphical objects like comment boxes are included in the code. * Fix On Unix systems, falling back to GTK2 when running drracket seems to completely fix the issue: PLT_GTK2=1 drracket Jaroslaw, I don't know about Windows but if you can do something like this when running drracket, you may fix the problem by now. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

[racket-users] Strange gray lines in DrRacket editor
Recently I installed racket 6.10 (Windows version) on my new laptop (OS is Windows 10 Creators Update) and I noticed strange gray boxes when writing programs in the DrRacket editor (see picture attached). I assume it's related to my DPI settings which is set to 125% in the Display settings dialog, and the resolution is set to 1920 x 1080 which is equal to real resolution on my 14' laptop screen. Since other apps on the same machine don't exhibit any display problems, i suppose this is a bug in DrRacket so I report it here in the hope that it will be resolved in the new version of DrRacket.
