Link to the refresh rate bug: https://bugs.kde.org/show_bug.cgi?id=438156 Only happens with OpenGL 3.0, which crashes after re-enabling a secondary monitor as described here: https://bugs.kde.org/show_bug.cgi?id=438157 Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with Plasma 5.25 or 5.26? If it is, please change the status to CONFIRMED when replying. If not, or if you can't because you no longer use this setup, you can change the status to RESOLVED WORKSFORME. Thanks a lot! *** This bug has been marked as a duplicate of bug 455394 *** |
Created attachment 139032 [details] Commented and edited screenshot to show the bug SUMMARY I have 2 monitors connected, primary on the left and secondary on the right. I regularly turn the secondary monitor off to save power. After re-enabling it, the alignment of the monitors is 1 pixel off, so that the most right pixel row of the left monitor is displayed on the right monitor. In other words, if I have a maximized window on the left monitor, the right pixel border of that window is displayed on the right monitor instead of the left. The attached screenshot may explain this bug a little better STEPS TO REPRODUCE 1. Connect two monitors, primary on the left and secondary on the right. 2. Disable the right monitor and immediately re-enable it. OBSERVED RESULT The monitors are aligned as described in the summary. EXPECTED RESULT The monitors should be aligned as before. SOFTWARE/OS VERSIONS Linux/KDE Plasma: 5.21.5, Manjaro (available in About System) KDE Plasma Version: 5.21.5 KDE Frameworks Version: 5.82.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION There is also another bug after re-enabling a monitor: the wrong refresh rate is selected (50 Hz instead of 60 Hz). I will open another bug report for this.
