3.2.8: CLAP: Wrong rendering in Reaper

[koalastudio72]

Hi, I have the issue that the CLAP-Version in 3.2.8 doesn't fit in the plugin window in Reaper 6.73 (WIN-Version).

Thank you.

what is your display scale factor? seems to be different than 100%

[koalastudio72]

Thanks for the quick reply.

My scale factor: 125% But the VST2/VST3 versions fit well with this scale factor. When I switch to 100% all the text is unfortunately too small on a 15 inch laptop display. Any idea ?

Might be a bug in reaper since the other versions work correctly. Do you have any other host installed that can also load clap in order to verify this? Bitwig or MultitrackStudio

[koalastudio72]

Unfortunately not. Certainly I can live with the other versions and wait until the CLAP-versions work correct in Reaper. Nevertheless thank you for you support.

Same thing happens for LV2 too

I think I know why, but no time to investigate it proper at the moment.

I can reproduce it on Linux with Reaper, but not with Bitwig. Applying this patch to DPF makes the plugin size correct in Reaper and doesn't affect it in Bitwig. However, I have no idea if this is just a hack that fixes the problem for this plugin, or if this is (part of) a proper fix for a bug in DPF.
