It seems that the accessibility effect 'track mouse' does not work anymore (regression after I updated from 4.8.4 to 4.9.0). I had it assigned to the the modifier keys CTRL+META. I tried to assign a key combination to it, but the stars encircling the mouse cursor still don't show when pressing it. Reproducible: Always Steps to Reproduce: 1. enable track mouse effect, e.g. setting the modifier keys CTRL and META as shortcut 2. press CTRL+META Actual Results: No visible change on the screen Expected Results: Yellow stars should have been circling around the mouse cursor (or at least some other effect making the mouse cursor discoverable more easily).
Please have a close look and start moving the mouse when you pressed the shortcut. It's no longer a circle of stars.
First off: I logged into my desktop freshly today and I saw the new effect when pressing the shortcut. It is harder to see than the circling stars, maybe because it is smaller. I like the fact that it has two 'colors' (b&w) though, because it can probably be seen on differently colored backgrounds – is there an easy way to configure/program the colors/sizes/number of bars? The other thing is: the effect seems to stop working once I use the window switcher (ALT+TAB). In one test, I had the impression that the effect was just a bit more faded after using the switcher once and then it disappeared completely after another switching (but I might be mistaken on this since I could not really reproduce this). What I could reproduce is: 1. fresh login: effect works 2. hit ALT+TAB to display the window switcher Result: effect stops working, I found no way to re-enable it other than to logout/login
> 2. hit ALT+TAB to display the window switcher > Result: effect stops working, I found no way to re-enable it other than to > logout/login which window switcher are you using? Do you press Alt+Tab while the track mouse is shown or how do you do that?
I'm using box switch. I do not use the effect while doing ALT+TAB, but just hit ALT+TAB to display the switcher, then try the effect again, which does not show anymore. It is really strange: sometimes the effect seems to disappear completely, sometimes it is just VERY translucent. Btw., I found a way to re-enable it other than to logout/login: zoom the whole desktop, then the effect works again (also in the unzoomed state). But as soon as I use the box switch again, there are these strange goings on with the track effect.
> I'm using box switch. that's not possible. Box Switch is no longer used as an alt+tab effect. Could you please provide an overview of all the settings regarding Alt+Tab you have done?
(In reply to comment #2) > is there an easy way to configure/program the colors/sizes/number of bars? /usr/share/apps/kwin/tm_inner.png /usr/share/apps/kwin/tm_outer.png override them in ~/.kde/share/apps/kwin - I'm not sure about size change handling atm - you'll have to try ;-)
@Thomas: Thanks for the information; I'll have a look at it later. @Martin: I don't really know what to tell you other than: I've checked 'Box Switch' on the Configure desktop effects page. I've now unchecked this, logged out/in, but the behavior did not change (box switch seems to be active still).

Alt+F3 -> More Actions -> Window Manager Settings... -> Task Switcher Please screenshot this window

Yet, I don't see the mouse tracking.
Opacity changes come with fading in/out non clients (reliably with popup menus, the switcher falls into that category) and GLSL -> the shaders are not correctly "popped" This is possibly a more general problem.
I discovered that using e.g. the 'Large icons' switcher, this does not seem to happen. Also, https://bugs.kde.org/show_bug.cgi?id=304435 does not happen anymore. Once I choose the thumbnail switcher again, however, I see both of these strange phenomena.
Created attachment 73226 [details] Possible patch If you have any chance, please try the attached patch. I'm quite confident that it will fix the issue, but I am myself not able to reproduce the issue, so I cannot test it.
"Ship It!" - works for me. *cough* shader->setUniform(GLShader::ModulationConstant, QVector4D(1.0));? *cough* shader->setUniform(GLShader::ModulationConstant, QVector4D(1.0, 1.0, 1.0, 1.0));! ;-)
I'm wondering how that could compile here...

Reset shader state in TrackMouse effect prior to render it The Shader might have left-overs from last usage which might cause the effect to not work properly.
