Original GitHub issue: https://github.com/debauchee/barrier/issues/769

Operating Systems

Server: Manjaro 20.0.3 Lysia

Client: windows 10 v2004

Barrier Version

2.3.2-1

Steps to reproduce bug

When I first selected a piece of text (not copied to the clipboard), then took a screenshot (the image data was copied to the clipboard), and then switched to the windows screen, the text of the selected text appeared in the windows clipboard, but there was no image data.

Other info

Later I learned that X under Linux does have two clipboards: https://unix.stackexchange.com/questions/139191/whats-the-difference-between-primary-selection-and-clipboard-buffer. Knowing this feature, I slightly changed the source code to ignore the clipboard called primary:

diff -r barrier-2.3.2/src/lib/server/Server.cpp /tmp/b/barrier-2.3.2/src/lib/server/Server.cpp
490c490
<for (ClipboardID id = 0; id <kClipboardEnd; ++id) {
---
> for (ClipboardID id = 0; id <kClipboardEnd-1; ++id) {
512c512
<for (ClipboardID id = 0; id <kClipboardEnd; ++id) {
---
> for (ClipboardID id = 0; id <kClipboardEnd-1; ++id) {

Sorry, I only learned C language at the university for dozens of classes, but the changes did work.

I'm not sure if I just encountered this problem, maybe this issue can help some people.
