I'm using SW 2018 SP3 and have a UHD screen (3200 x 1800). Unfortunately after upgrading (from 2017 to 2018), it seems the measure tool font is much too large (see attachment). I noticed that font sizing in the measure tool was something changed in 2018, but even with the smallest font allowable, it's still too large. Any way to fix this? It looks really ugly.
Are you using 4K monitor? There is a SPR 1051454: Measure tool text is very large in SW 2018 with 4k monitor.
You can contact your VAR to attach your company to this SPR. This should speed up the work on the fix.
Best regards,
Alek
