Hello,
I have an A750 that is running great on KDE Plasma in a fully updated Tumbleweed. Hardware encoding, OpenCL/GL and everything appears to be working properly. The motherboard is a ASUS Prime X570-Pro with a Ryzen 7 5700X, so there is no integrated graphics to interfere with anything. Re-sizable Bar is enabled. The monitor is a Samsung UR55 4K using the display port.
When selecting Rectangular Region to take a screenshot with Spectacle, I get a bright white fog over light colored windows to the point it’s hardly usable (it makes black text on a white background lighter). Changing “Use light background” in Spectacle Configure menu doesn’t appear to make any difference either way.
Using “Window Under Cursor” doesn’t capture the desired window but just a section of the screen with part of the window. Using Active Window works. Full Screen with a 1 second delay works. I cloned my Tumbleweed NVMe SSD to a USB enclosure and plugged it into my wife’s computer and Spectacle worked great. She has the exact same hardware except she has a RX580.
Also, using ALT+Shift+F12 to turn off the compositor fixes Spectacle with the A750. I’ve studied this pretty good and haven’t found anyone with the same problem. I also installed Spectacle from Mageia 9 and it has the same issues.
I didn’t not try HDMI yet, I forgot. I have not noticed any problems with Blender, Darktable, GIMP, VLC or the desktop etc. I did find wherhe the Spectacle developers made changes to how it displays the selection area but that’s been a couple of months ago.
I’m open to ideas from anyone who may have a clue what the problem is.
Thank you.
