Apache Guacamole XRDP desktop shows sometimes blurry

I'm using Apache Guacamole 1.2.0 and XRDP 0.9.12 on Ubuntu 20.04.

When looking at the remote desktop the fonts are shown sometimes reasonably sharp (alas still less than when opening an RDP connection directly), but often become blurry/blocky, as shown in the following screenshot.

It's possible to "provoke" this by letting the browser window loosing the input focus. But it also happens while working on the remote desktop. By triggerings repaints (e.g. by going with the mouse over the text) the fonts become sharp again at the repainted screen regions while staying blurry at the other screen regions.

The RDP connection settings in Guacamole are configured like this:

I played a bit with the font smoothing and caching options, but could not improve the situation. Is there any way to keep the fonts from "going blurry"?

Best regards,

Solution

  • I reinstalled with compiled versions xrdp 0.9.14 and xorgxrdp 0.2.14 - I had to do this anyway, because file sharing does not work between Guacamole and xrdp 0.9.12.

    As a "side effect", the blocky/blurry appearance is gone now, too. Either it has been fixed with the newer version or my old installation was somehow faulty.
