Created attachment 167628 [details] KDE 5 behaviour SUMMARY When using Task Manager (not Icons-Only Task Manager) and opening many windows (with no grouping), the point where it switches from showing the icon and the window name to just showing the icon is too soon in Plasma 6, compared to Plasma 5. STEPS TO REPRODUCE In both Plasma 5 and Plasma 6: 1. Choose Task Manager from the Alternatives popup 2. Open multiple windows 3. Count how many you can open before the window name disappears from the task manager buttons OBSERVED RESULT The number of windows you can open in Plasma 6 before it drops the window name from the task manager buttons is less than in Plasma 5. (The actual numbers will depend on screen resolution etc.) EXPECTED RESULT The number of windows you can open in Plasma 6 before it drops the window name from the task manager buttons is the same as in Plasma 5. SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20240321 KDE Plasma Version: 6.0.2 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 Kernel Version: 6.8.1-1-default (64-bit) Graphics Platform: X11 Processors: 4 × Intel® Core™ i5-7200U CPU @ 2.50GHz Memory: 15.5 GiB of RAM Graphics Processor: Mesa Intel® HD Graphics 620 Manufacturer: HP Product Name: HP ProBook 450 G4 ADDITIONAL INFORMATION See the attached screencasts, taken from VirtualBox running the openSUSE Leap 15.5 Live KDE iso (for Plasma 5) and the openSUSE Tumbleweed KDE iso (for Plasma 6). I have shown the configuration of task manager, to try and make the screencasts comparable.

Indeed, setting the width for vertical task bar to 100px makes the name appear, setting it lower shows only icon.

A vertical task bar is a good way to illustrate the change, and changing the width of that is probably easier as a reproduction method than my "open multiple windows until you see the problem" method. Do you know what was the minimum vertical task bar width that would still show the window titles in Plasma 5?
As I wrote above: starting 100px width windows names are starting to showing up.

KDE 5: 74px - no naming 76 - naming appears
