I have a 4K monitor (3840x2160) at 29 inches. The Bisq app’s fonts are WAAAAAAAAAAY too small. Attached is a screen shot of the Bisq app on the left and a similar UI with a usable font size on the right (Coinbase Pro trading platform).
Also, the Bisq right-click menu from its icon in the Linux Panel (bottom-right, by the system clock, not pictured here) is way too tiny too. All other software I have installed obeys my OS user preferences for fonts. It would be very helpful if the Bisq desktop app did the same.
